Much of the original Mac ROM and the display subroutine were written by Andy Hertzfeld who left Apple and founded Radius in 1986. Radius did a lot of work for Apple on the Mac II and SE.
In 1992 while working for a government contractor, as an intern, I scored a Mac II FX filled it with new bus cards and had an Apple two-page display black and white, two 13-in Apple displays on top of that, and two 17-in color displays on either side. Five monitors on a McIntosh in 1991. Every senior person in the office had me hooking up dual and triple monitors to their Macs after that.
Did you also use the screen extending extension MaxAppleView, that would extend the screen area from 640x480 to 705x500 or something when using the original Apple color graphics cards? Not quite the 800x600? or 1024x768? of the 17" display, but great on the good old Sony Trinitron socalled 13" RGB display. What a great display that was, just as its later, larger "brother", the 17" Trinitron.
At $4,000 in 1986, that’s the equivalent of an $11,000 upgrade! I interned at a well funded research lab in 1990 that had Mac IIfx’s, but none of them were equipped in a multi monitor configuration. This is really amazing to see on a Mac Plus!
Hi Adrian, long time viewer - love the videos! In the "Edit Transform" dialog (CTRL + E) of your capture source on that scene in OBS, set `Bounding Box Type` to `Scale to inner bounds`. That'll scale to the size of your space no matter what res or aspect ratio you're using. Sincerely, an OBS developer.
The capability to handle multiple monitors was baked into the Mac from the beginning. The screen was defined as a quickdraw object, so it could be any shape you could make with quickdraw shapes. You could, for example, define the screen to be a circle, or half a circle, or a square and half a circle. If I remember correctly, the Mac screen was actually defined as a rectangle with rounded corners. So putting two rectangles together for a two display system was simplicity itself. The big obstacle Radius faced wasn't getting the OS (and apps) to work with multiple displays it was getting the hardware to support a second monitor. Also note, most applications worked with the Radius display just fine, the problem apps were ones that didn't follow the Apple guidelines -- most were soon updated and by the time the Mac II and "official" multi-monitor support came out there were basically no software issues.
@@8BitNaptime Not quite the same thing. The PC let you put whatever you want in any free memory or IO region - be it video, sound, network, or whatever you can think of.

I wonder why Apple CloseView didn't work with it (as called out in the ReadMe). I presume the magnification effect probably worked on the graphics on a fairly low level and just didn't know how to deal with the card.
Ohhhh, I always wondered, when looking at a classic Mac's video output on a flat-panel display, why it had rounded corners! That would explain it, though I wonder why they did it that way?

We had a setup like this at my rural Indiana Junior High School around 1992 using the same setup. It was replaced during my second year with an updated (still Mac) version. I am unsure if it was the Radius, though (memory fades).. It was in a teacher resource room (away from students), but I had an in with our Librarian and she let me use it a few times after regular school hours. This IS what sealed the deal for me on having multiple monitors.... I had my own dual monitors by 1998 (PC), and I have four now. I will never go back!!! Thanks Adrian!
Radius was founded by the hardware designer of the original Macintosh, Burrell Smith, later joined by other talents like one of the original software developers, Andy Hertzfeld. That's why their products were so amazing.
Before I subscribed and binged your content, this is the reason why I started watching. this is the Happiness, The Joy the Experimentation....everything this... this is what... this is beautiful. I've missed you.
I knew a guy who bought the Radius. I bought his Mac Plus ROMs from him and plugged them into my Spectre cart on my Atari ST, giving me Mac compatibility on my ST. I had a 4Mb expansion card, 4096 color mod, 16MHz 68000 upgrade, stereo mod, and 20Mb hard drive. I could also run MS-DOS on my ST, and had a switchbox so I could toggle between color and monochrome monitors. Stuff for the ST was actually kind of cheap, so I actually did most of this for less than the cost of a Mac at the time. Loved that system, but eventually had to ditch it all when Win95 came out and I needed Internet access.
I remember upgrading the EPROMs on a couple of those for customers but the two pieces that really stuck in my head were the installation steps of threading the monitor cable through the security slot, and using needle nose pliers to attach those two little springs being used as jumpers to the motherboard.
@@adriansdigitalbasement In the 1990ish timeframe I remember a sort of a "clamp on top" socket on the bottom of the Radius board made from the same green plastic as the VRAM and CPU sockets on your board which would push over the top of the soldered CPU and come to rest against the motherboard. It was a bear to get on the first time and it never struck me as a good mechanical connection. Then you needed to attach the two springs. We were the official Radius shop (and the official Apple V.A.R.) for San Francisco, but we didn't do any board level soldering and Apple would have had our hides if we were retrofitting boards with a soldering iron.
It was probably around 1989, but my first Macintosh experience was this exact compact Mac/vertical monitor dual display setup. I would have been around 14. My dad was a printer and one summer holiday he arranged a week’s work experience for me at his printing firm. Most of the week was spent shadowing the guys working the huge Heidelberg presses, but on the Friday I got plonked in front of the Mac in their small office and was left on my own. It ran some kind of DTP software and I remember mocking-up a newspaper front page with some disparaging headline about the company. I don’t remember what model Macintosh it was, but it was 100% this setup. The external monitor was on the right, the way you had it. Since it was one of my earliest computing experiences, I didn’t think it was unusual at all, but it was very cool and it got me started on a thirty+ year Macintosh journey. Thanks for sharing this. You definitely need to source one of those vertical monitors.
You are a great asset to the tech world. Sometimes vintage machines have a "thing about them" that cannot be matched by modern hardware. You are excellent and keep up the great work!
The thing I admire the most from you is your seemingly unlimited patience, persistence, and perseverance. So many times I watch your videos and think "I would have given up a long time ago", but your attitude is amazing. I must say that it makes me persist through many debugging sessions where I have to find problems with somebody's code or system, knowing that you would also not just give up.
Wow that's amazing. I never thought that the older Macintosh all in one models like the Macintosh Plus have the ability to display a second image let alone with a special multivideo card like the Radius Display. That's freaking cool and honestly way ahead of it's time.
The funny thing is that the enabling technology of the GrafPort behind the scenes of these multi-monitor setups predates the Macintosh, from when QuickDraw was called LisaGraf.
I liked the beginning of this episode...it reminded me of the opening scene from a Computer Chronicles episode from PBS. Plus we got to see another part of your house outside of the basement!
As a previous commenter mentioned, this was possible due to a deep understanding of the Mac and its internals. When Jobs left Apple two bands formed. 1) those that thought that the Mac API were perfect and the monolith architecture just needed extension hardware to move forward. 2) those that thought the Macintosh model was doomed and things needed to start from scratch to form a real modern system. The first camp split in two as the base team left Apple to form extension hardware for the nascent graphical and desktop publishing area. One such company wax Radius which also offered “the Pivot” which was a monitor that switched from portrait to landscape. The other camp created the Mac II which was workstation class but never really had an OS to match. The start from scratch camp joined Jobs and created NeXT, which tried to be better than the Macintosh II and the SUNstations and Silicon Graphics but failed when these last two switched to RISC.
At the planetarium I worked at in the late 80's, early 90's, we had a Mac Plus and Radius portrait display and used Aldus Pagemaker to do our star chars and flyers. It was fantastic.
I had a Radius display as a second monitor on my Mac IIcx - it was the rotating Radius monitor with 16 greyscale support. I believe you could upgrade the ram to 256 greys but I didn't do this. I used it with Emagic Logic for viewing and editing music scores (midi back then). It was awesome. Nice to be reminded of this tech!
I remember when I was a Cub Scout, a fellow scout's mom ran a desktop publishing business of some kind from their house, using either that setup or one very much like it. I remember that the secondary monitor seemed HUGE at the time, although it's probably laughably small (screen-size, I mean) compared to popular sizes for modern LCD panels. She had "fancy" professional publishing software and a laser printer (the first I'd ever seen) loaded with glossy paper. She made simple signs for us at our request one day, and it felt like getting your own, personalized magazine page. Now, they were super-duper plain and boring compared to what you could do with free software and a nice sheet of glossy paper in a much, much cheaper modern printer today, but they were light-years away from what most of us could do at home or even at school at the time.
That is pretty darn amazing Adrian. Wow. I remember in '86 I was happy to have a single 4 color CGA monitor. I wasn't a Mac guy, please don't be mad, my mom ran Unisys at work (I think that was in 86 or so, Unix system before Linux came around) and we had an IBM clone at home, an XT back then.. man this is absolutely amazing!!
It is really exciting to see this card working again after so many years. Your enthusiasm is contagious 😄 27:45 I think the slider has something to do with speed, because of the symbols (rabbit and turtle), maybe the monitor's refresh rate.
I had a Macintosh SE back in the day and had added a second display to it through the use of a "ScuzzyGraph II" by Aura systems. It plugged into the SCSI port and a system extension sent QuickDraw commands to the unit. Performance was sufficient for word processing and other tasks the Mac SE was capable of, though a bit slower than the onboard display - hard to notice though. The performance differential became more apparent when I had gotten a Mac LC II and set it up on there as a lark. External video was a LOT slower than the new video hardware on the LC. Still a neat piece of history. Let me add a second display to my Mac SE without even having to use the PDS slot.
Mac Plus was first computer that got paid to write software for. I was assigned task of creating a kiosk interface to control a laser photo plotter for printing PCBs from gerber files. In 1986 I created a desktop UI for the Mac that looked very much like Windows 95 desktop - Start menu in bottom left corner that sprouted a heirachical menu system - nearly a decade before MS did similar with Windows. The point being is that all these crucial data structures were accessible and could be morphed to create a desktop experience radically different from the stock Apple desktop. The 80s was just a really cool time to be technically involved in the computer industry.
I remember Radius, they were doing some exciting things back then-like LGR's Radius Pivot monitor that has that special card and monitor with that mercury switch that would auto-rotate the screen based on the position of the monitor, as long as the software supported it.
OMG, I had that SAME set up not only with the IIci with a huge 21" monochrome monitor, but with an SE-30 with the additional portrait monitor. I was lucky enough to scrounge the main warehouse of my school district and cobbled together a computer station with a mix of Apple-IIs, 2 Mac SE's, an SE--30, and a Mac II'ci. As I teach Social Science, I had the classic "Oregon & Amazon Trial" games with a few others that I used frequently. We actually had tournaments in my classes to earn extra grades! That was before The District contracted for a network with Dell Computers! Such a sad day they took away my Macs, including mine! ☹
I do recall those print ads for that dual monitor system. Meanwhile the commercial photo lab I worked at relied on TRS-80's for critical tasks. Mac stuff was like a dream.
Well done 👍 Amazing to see a 2 screen mac system from 1986 - I was 15 that time an inspired by my Atari 800 XL that time and saving up money fro the ST..
I remember when I was in Elementary School they used Mac computers similar to this one except the monitor was more transparent and SUPPOSED to look kid friendly still wish I could be an Elementary kid I hate how fast time flies being older now I'm 30 this is like a time capsule to me thanks for uploading!
Ayy! Very cool video, Adrian! I don't know if you recall, but back in '21 you and I emailed about this a bit. Such a cool gadget for the time. Thoroughly enjoyed this (like all your videos :) )
I remember installing those miserable bleeps when I worked at a DOE lab located in Northern California. They were a royal pain to do, so of course every secretary needed one. There were dozens of clip on expansion boards for the Plus series; but I was so happy when the SE came out with the port. I was on a first name basis with about a dozen people at Radius because we had so many of their products installed. The head of Radius knew the Mac video ROM forward and backward since he wrote most of the code. We were the beta tester for the Radius Pivot- we might have even initiated the creation because secretaries really wanted to work in Portrait to type documents, but go widescreen for spreadsheets.
6:23 seen quite a few of those portrait monitors at schools, really takes me back. Never seen one hooked up to a Mac plus, they was always hooked up to a different machine and was the only monitor.
I used to work at a computer store in the 1980's called Mac Corner in Gaithersburg Maryland where we installed this upgrade for both the Mac Plus and the Mac SE.
This is so nerdy, I love it. I really enjoyed watching this video, coming from working on Macs from 1990. I remember going to my friends house in 1985 and messing around on the computer that you are working on or the version before it. It was a revolutionary appliance, like our first microwave.
Another flashback thanks to Adrian, I love this channel for that. 🥰 I remember using a Mac with this additional screen for our school newspaper in '88.
My parents had a Mac 128k in 1984; they had it upgraded to a 512k motherboard by Apple in 1986, then to a Mac Plus when that became possible. They also had a MegaScreen monitor hooked up to it! I never realized how much money all that cost them back then. Whew!
We had a similar model in 1990 for brochure editing. Nice system, super-fast and error free. Although, when we moved to page-condensing, the whole system would sometimes freeze. We'd lose a lot of work and have to start over. That did happen a lot.
That’s really cool, as exactly that configuration MacPlus, Radius video card and a Radius Portrait Monitor was my first ever work computer when I started to work as a Technical Writer in 1990. We ran RagTime and Canvas on it and had a shared Apple Laser printer via AppleTalk. Worked pretty well.
Back in late 80's a mate had an enhanced 512, with this card and monitor. It was soooo cool, though compared to my Plus(w/4MB) it was also very clunky and slow. Was wonderful to watch you bring back something obscure from my past back to life. Thank you!
Oh, this was an awesome journey! Soo many times I was thinking things like: „Oh, you should open an IDE on that“ and next thing you do is exactly that 😊 Super fun video, maybe even one of the best you‘ve uploaded so far. Thank you!
I am constantly floored at the depth of knowledge Adrian and other members of the community have about this kind of stuff. It's absolutely wild that you can just output direct HDMI video from a standalone Mac Plus motherboard. And that's not even the most impressive part of any of this.
I remember some smaller advertising agencies using the SE with big, very expansive monitors, often HiRes-B&W - with both monitors active. And that was in the early nineties...
We used a Radius monitor hooked up to a MacSE at my office in the mid-90's. We used Ready, Set, Go to create and publish the association newsletter. Once we had it set there and since RSG ran off of floppy we would go to a copy place that had macs and laser printers to do final tweaking and printing of the final copy. This copy would be taken to our printer to print and bind. The monitor really helped in layout and minimize the amount of tweaking we had to do. We also used a couple of accelerator cards (020 and 030) in a plus and SE to speed those up too. Not to mention the Appletalk network that we ran throughout the office. It really was ahead of its time and made us super productive for an extremely small staff. Nice trip down the memory lane.
I remember seeing this setup at a local computer shop when I was in college. I thought these were one of the coolest things I ever saw using a all in one style Mac.
Super cool video, awesome work sleuthing out the video signals! I really really love how genuinely excited you get when you’re working with vintage gear like this and start to approach a solution, it reminds me of how excited I was about computers in the 80s and 90s. Those power supply and video kit projects you mentioned are really neat too! Love the video, keep ‘em coming!
It’s really cool to see this. My best friends mom was a lawyer and had a setup like this in her home office. It was always so cool to see 2 screens on her desktop. We weren’t allowed to play on her computer though :)
Installing that card was a challenge. I worked for Radius from 92-97 in tech support, and we were challenged when Apple would make changes to the OS, and we needed to adapt quickly to avoid people calling in...
my Mac SE/30 came with a Radius card, I think it's a Two-Page Display card, which had a single BNC connector output. It apparently outputs either black and white or grayscale composite video at 1152x882. I pulled it from my Mac, because I don't think I'll ever find a matching monitor, or a solution to convert the video signal to something more common, like VGA or HDMI.
Really cool episode. I'm one of those careful weirdos who build things in doubles most of the time so I could have deal with this with my 2 RGBtoHDMIs too. Your electronics insight about the 5V sense pin puts you in the next level - that would have been a stone wall for me.
As a sysadmin for an engineering office (i'm not sure if the translation brings over correctly, what an "Ingenieurbüro" in the DACH region does, from what i read, "engineering offices" in the US are different) that's over 35 years in the business, i've got a few seniors that told me stories about working with MicroStation in 1987 on Macintosh and after 1989 on PC-AT with two monitors. Apparently it was an absolute pain in the ass to set up, but if it worked, it was amazing to work with. Apparently there also was a VAX version wich supported even more monitors, same as UNIX. It's pretty impressive that some issues still exist, over 35 Years later...
My first computer was a VERY kitted out Mac Plus... which as a mid 80s baby, by the time I had it in the early 90s, it was a little long in the tooth. As at school we had LC's, LCII, III's, etc... But, I was able to utilize SO much of the LC software, and my own, back and forth... that it really gave me an appreciation for the early apple / mac ecosystem. I enjoyed the heck out of it really, and my dad was the one who made it all possible... as at the time he did his own painting and remodeling thing, and being that I was into electronics and computers, he (unbeknownst to me) took on a job where a good portion of the payment was in trade, and that trade was the Mac Plus, external SCSI HDD, multiple external apple FDD's, and just boxes and boxes and boxes (all og boxes no less) of software. And I mean original apple hardware boxes for the computer, the image writer (original, later got an image writer II from school due to friendly relationships with staff), the HDD, and all of the other hardware accessories... as well as all of the hundreds of original boxes for the, well, basically every single piece of software ever written for the early Mac ecosystem. The guy my dad did the job for, who traded the computer and software for the work, he was some inventor.. who held patents for the original miracle ear, some derivative of space food, laser blocking license plate covers so laser speed detectors couldn't see you... and a bunch more. And he used the mac plus it seems, to develop a lot of this stuff. From cad titles, to print and design, to software development, to games.... as all these types did for sure enjoy a good computer game back then, and there were cases of disks that were nothing but. But all of the spiral bound books for the hardware and software alone would bring a fortune today. And of course, not seeing what it was worth, and after getting my first "actual computer" in 97 (Packard Bell 233MMX), I actually did the unthinkable and gave it all away. Ever since I've been piecing back together bits and pieces of tech I had as a kid... but the mac plus still eludes me. They are often around, with saved searches and listings, even locally, usually being a thing that exists... but I've honestly found it easier to just grab all of the other items in whatever condition they happen to be in, fixing them up, stowing them away... stockpiling my old tech collection. But the mac plus... every one that I see for sale, they all fall short somehow. This one that I had, it was so complete... I just know that I'll never have that again. So I just never pull the trigger, and haven't even tried. BUT... seeing this... man. I didn't have any idea this was even possible! All of the things I'd done with mine over the years, and all of the hardware I had... but I NEVER knew it could do this!
Back in the '90s common Windows X86 computers could do a second monitor, but to your point they were not graphical, only raster. I set up a second monitor on my boss's computer that would run under Borland's C++ development environment that allowed him to see debug information real time while developing Windows code. It was just a raster system and we had an extra monitor lying around so I bodged it up for him one day when he was out and he loved it.
I love it that you take us through all the processes and all the discoveries, faults and happy moments as well. When something turns out to be working I too feel the satisfaction and joy of your work :)
Very much enjoyed this video, Adrian -- including your never-ending effervescence for this seminal tech. It also speaks volumes about how forward-thinking the original Mac team were. Andy Herzfeld (Mac OS) and Burrel Smith (Mac hardware) not only founded Radius to realise the full potential of the Mac's system software, but Andy and Bill Atkinson (Mac graphics guru and MacPaint author) also founded General Magic, the very first "iPhone"-like PDA.
Much of the original Mac ROM and the display subroutine were written by Andy Hertzfeld who left Apple and founded Radius in 1986. Radius did a lot of work for Apple on the Mac II and SE.
Ah well that really explains things a lot then!

Wow that's amazing. I never thought that the older Macintosh all in one models like the Macintosh Plus have the ability to display a second image let alone with a special multivideo card like the Radius Display. That's freaking cool and honestly way ahead of it's time.
The funny thing is that the enabling technology of the GrafPort behind the scenes of these multi-monitor setups predates the Macintosh, from when QuickDraw was called LisaGraf.
I liked the beginning of this episode...it reminded me of the opening scene from a Computer Chronicles episode from PBS. Plus we got to see another part of your house outside of the basement!
As a previous commenter mentioned, this was possible due to a deep understanding of the Mac and its internals.
When Jobs left Apple two bands formed. 1) those that thought that the Mac API were perfect and the monolith architecture just needed extension hardware to move forward. 2) those that thought the Macintosh model was doomed and things needed to start from scratch to form a real modern system.
The first camp split in two as the base team left Apple to form extension hardware for the nascent graphical and desktop publishing area. One such company wax Radius which also offered “the Pivot” which was a monitor that switched from portrait to landscape.
The other camp created the Mac II which was workstation class but never really had an OS to match.
The start from scratch camp joined Jobs and created NeXT, which tried to be better than the Macintosh II and the SUNstations and Silicon Graphics but failed when these last two switched to RISC.
This is some Grand High Nerdery, Adrian. Great work, getting it going with that bodged setup!
Nice work. Love how the radius window has that fancy corner-flair.
At the planetarium I worked at in the late 80's, early 90's, we had a Mac Plus and Radius portrait display and used Aldus Pagemaker to do our star chars and flyers. It was fantastic.
I had a Radius display as a second monitor on my Mac IIcx - it was the rotating Radius monitor with 16 greyscale support. I believe you could upgrade the ram to 256 greys but I didn't do this. I used it with Emagic Logic for viewing and editing music scores (midi back then). It was awesome. Nice to be reminded of this tech!
I think I was nearly as excited as you were when I saw that that gray screen with the radius splash screen!
I also had a Mac 512k with a internal hard drive. I unfortunately do not have it anymore, I've been on the search ever since.
Great video, btw.
Enjoy your vides. Thanks for making them and posting.
My god this channel is such a gem. Ty Adrian.
I remember when I was a Cub Scout, a fellow scout's mom ran a desktop publishing business of some kind from their house, using either that setup or one very much like it. I remember that the secondary monitor seemed HUGE at the time, although it's probably laughably small (screen-size, I mean) compared to popular sizes for modern LCD panels. She had "fancy" professional publishing software and a laser printer (the first I'd ever seen) loaded with glossy paper. She made simple signs for us at our request one day, and it felt like getting your own, personalized magazine page. Now, they were super-duper plain and boring compared to what you could do with free software and a nice sheet of glossy paper in a much, much cheaper modern printer today, but they were light-years away from what most of us could do at home or even at school at the time.
That is pretty darn amazing Adrian. Wow. I remember in '86 I was happy to have a single 4 color CGA monitor. I wasn't a Mac guy, please don't be mad, my mom ran Unisys at work (I think that was in 86 or so, Unix system before Linux came around) and we had an IBM clone at home, an XT back then.. man this is absolutely amazing!!
I wanted one of those for my Mac Plus so bad. Radius rocked!
It is really exciting to see this card working again after so many years. Your enthusiasm is contagious 😄 27:45 I think the slider has something to do with speed, because of the symbols (rabbit and turtle), maybe the monitor's refresh rate.
I had a Macintosh SE back in the day and had added a second display to it through the use of a "ScuzzyGraph II" by Aura systems. It plugged into the SCSI port and a system extension sent QuickDraw commands to the unit. Performance was sufficient for word processing and other tasks the Mac SE was capable of, though a bit slower than the onboard display - hard to notice though.
The performance differential became more apparent when I had gotten a Mac LC II and set it up on there as a lark. External video was a LOT slower than the new video hardware on the LC.
Still a neat piece of history. Let me add a second display to my Mac SE without even having to use the PDS slot.
Mac Plus was first computer that got paid to write software for. I was assigned task of creating a kiosk interface to control a laser photo plotter for printing PCBs from gerber files. In 1986 I created a desktop UI for the Mac that looked very much like Windows 95 desktop - Start menu in bottom left corner that sprouted a heirachical menu system - nearly a decade before MS did similar with Windows.
The point being is that all these crucial data structures were accessible and could be morphed to create a desktop experience radically different from the stock Apple desktop.
The 80s was just a really cool time to be technically involved in the computer industry.
I remember Radius, they were doing some exciting things back then-like LGR's Radius Pivot monitor that has that special card and monitor with that mercury switch that would auto-rotate the screen based on the position of the monitor, as long as the software supported it.
OMG, I had that SAME set up not only with the IIci with a huge 21" monochrome monitor, but with an SE-30 with the additional portrait monitor. I was lucky enough to scrounge the main warehouse of my school district and cobbled together a computer station with a mix of Apple-IIs, 2 Mac SE's, an SE--30, and a Mac II'ci. As I teach Social Science, I had the classic "Oregon & Amazon Trial" games with a few others that I used frequently. We actually had tournaments in my classes to earn extra grades!
That was before The District contracted for a network with Dell Computers!
Such a sad day they took away my Macs, including mine! ☹
Man, I love how PUMPED you get when things freakin' work!
Finally a video with more information about this. Ive been trying to get my plus to display on a second monitor for a while.
What is totally normal and boring in 2023 was Sci-Fi in 1986! Thanks for showing us the set!
I love the joy you find in projects like this, it's infectious :) Really interesting video.
I do recall those print ads for that dual monitor system.
Meanwhile the commercial photo lab I worked at relied on TRS-80's for critical tasks. Mac stuff was like a dream.
I really want one of these old Mac’s. They’re so cute and cool
Very exciting! And your excitement made me more excited! Well done!!
Holy moly moly..... I can't believe you have this working
I got a VGA and an MDA working on a 286-8 from 1985 ;) They were independent, to be clear, but you could output data to both of them at once.
Excellent work and a joy to watch! Very successful Digital archeology this was.
I LOVE your enthusiasm!
Well done 👍 Amazing to see a 2 screen mac system from 1986 - I was 15 that time an inspired by my Atari 800 XL that time and saving up money fro the ST..
Completely surreal ! This is great !
Thanx for an entertaining time trip. Love your enthusiasm!
I remember when I was in Elementary School they used Mac computers similar to this one except the monitor was more transparent and SUPPOSED to look kid friendly still wish I could be an Elementary kid I hate how fast time flies being older now I'm 30 this is like a time capsule to me thanks for uploading!
That's definetly a "IT FREAKIN WORKS!!!!" moment! So wholesome!
I'm not surprised that it was radius who made this product, especially with how pupular macintosh computers were in publishing.
Very cool!
Ayy! Very cool video, Adrian! I don't know if you recall, but back in '21 you and I emailed about this a bit. Such a cool gadget for the time. Thoroughly enjoyed this (like all your videos :) )
I remember installing those miserable bleeps when I worked at a DOE lab located in Northern California. They were a royal pain to do, so of course every secretary needed one. There were dozens of clip on expansion boards for the Plus series; but I was so happy when the SE came out with the port. I was on a first name basis with about a dozen people at Radius because we had so many of their products installed. The head of Radius knew the Mac video ROM forward and backward since he wrote most of the code.
We were the beta tester for the Radius Pivot- we might have even initiated the creation because secretaries really wanted to work in Portrait to type documents, but go widescreen for spreadsheets.
Outstanding. Real retro archaeology.
6:23 seen quite a few of those portrait monitors at schools, really takes me back. Never seen one hooked up to a Mac plus, they was always hooked up to a different machine and was the only monitor.
I used to work at a computer store in the 1980's called Mac Corner in Gaithersburg Maryland where we installed this upgrade for both the Mac Plus and the Mac SE.
This is so nerdy, I love it. I really enjoyed watching this video, coming from working on Macs from 1990. I remember going to my friends house in 1985 and messing around on the computer that you are working on or the version before it. It was a revolutionary appliance, like our first microwave.
Another flashback thanks to Adrian, I love this channel for that. 🥰
I remember using a Mac with this additional screen for our school newspaper in '88.
My parents had a Mac 128k in 1984; they had it upgraded to a 512k motherboard by Apple in 1986, then to a Mac Plus when that became possible. They also had a MegaScreen monitor hooked up to it! I never realized how much money all that cost them back then. Whew!
Fantastic video Adrian
We had a similar model in 1990 for brochure editing. Nice system, super-fast and error free. Although, when we moved to page-condensing, the whole system would sometimes freeze. We'd lose a lot of work and have to start over. That did happen a lot.
6:08 And that's exactly why that became the authors and publishers best friend.
That’s really cool, as exactly that configuration MacPlus, Radius video card and a Radius Portrait Monitor was my first ever work computer when I started to work as a Technical Writer in 1990. We ran RagTime and Canvas on it and had a shared Apple Laser printer via AppleTalk. Worked pretty well.
Back in late 80's a mate had an enhanced 512, with this card and monitor. It was soooo cool, though compared to my Plus(w/4MB) it was also very clunky and slow. Was wonderful to watch you bring back something obscure from my past back to life. Thank you!
I had one of those monitors and it was awesome for that era!
Oh, this was an awesome journey! Soo many times I was thinking things like: „Oh, you should open an IDE on that“ and next thing you do is exactly that 😊
Super fun video, maybe even one of the best you‘ve uploaded so far. Thank you!
my father and others at his office had this setup in the late 80s when he was working for EF Hutton
I am constantly floored at the depth of knowledge Adrian and other members of the community have about this kind of stuff. It's absolutely wild that you can just output direct HDMI video from a standalone Mac Plus motherboard. And that's not even the most impressive part of any of this.
Very cool. Thanks Adrian
This is much cooler than I imagined it would be before watching the video.
This is amazing for the time. There couldn't have been very many people using this setup.
I remember some smaller advertising agencies using the SE with big, very expansive monitors, often HiRes-B&W - with both monitors active. And that was in the early nineties...
back when i first did multi monitor it was back on my pentium 3 in 2001-2002 and the 2nd screen i used was my tv. was good to watch dvds on etc
This was interesting thanks for the video
We used a Radius monitor hooked up to a MacSE at my office in the mid-90's. We used Ready, Set, Go to create and publish the association newsletter. Once we had it set there and since RSG ran off of floppy we would go to a copy place that had macs and laser printers to do final tweaking and printing of the final copy. This copy would be taken to our printer to print and bind. The monitor really helped in layout and minimize the amount of tweaking we had to do. We also used a couple of accelerator cards (020 and 030) in a plus and SE to speed those up too. Not to mention the Appletalk network that we ran throughout the office. It really was ahead of its time and made us super productive for an extremely small staff. Nice trip down the memory lane.
Never heard of this, and surprisingly interesting. ❤
I remember seeing this setup at a local computer shop when I was in college.
I thought these were one of the coolest things I ever saw using a all in one style Mac.
Wow this is crazy sophisticated. I wish I had simple controls like that for Windows 10 multiple screens! Amazing level of refinement.
Super cool video, awesome work sleuthing out the video signals! I really really love how genuinely excited you get when you’re working with vintage gear like this and start to approach a solution, it reminds me of how excited I was about computers in the 80s and 90s. Those power supply and video kit projects you mentioned are really neat too! Love the video, keep ‘em coming!
Some of you best content yet!
It’s really cool to see this. My best friends mom was a lawyer and had a setup like this in her home office. It was always so cool to see 2 screens on her desktop. We weren’t allowed to play on her computer though :)
Installing that card was a challenge. I worked for Radius from 92-97 in tech support, and we were challenged when Apple would make changes to the OS, and we needed to adapt quickly to avoid people calling in...
This was awesome im glad u made this video
my Mac SE/30 came with a Radius card, I think it's a Two-Page Display card, which had a single BNC connector output. It apparently outputs either black and white or grayscale composite video at 1152x882. I pulled it from my Mac, because I don't think I'll ever find a matching monitor, or a solution to convert the video signal to something more common, like VGA or HDMI.
Well done Adrian we would of been blown away to have two working monitors back in the 1980s. Thank you
A very fun video, many thanks.
Very cool! How did I not know about this?😀 I think that I might have popped a spring if I'd have seen this in 86.
I was 21 in 1986 and that would have blown my mind. The first time I was exposed to multiple monitors was somewhere around 1990
Really cool episode. I'm one of those careful weirdos who build things in doubles most of the time so I could have deal with this with my 2 RGBtoHDMIs too.
Your electronics insight about the 5V sense pin puts you in the next level - that would have been a stone wall for me.
Brilliant video 😊
As a sysadmin for an engineering office (i'm not sure if the translation brings over correctly, what an "Ingenieurbüro" in the DACH region does, from what i read, "engineering offices" in the US are different) that's over 35 years in the business, i've got a few seniors that told me stories about working with MicroStation in 1987 on Macintosh and after 1989 on PC-AT with two monitors. Apparently it was an absolute pain in the ass to set up, but if it worked, it was amazing to work with. Apparently there also was a VAX version wich supported even more monitors, same as UNIX. It's pretty impressive that some issues still exist, over 35 Years later...
My first computer was a VERY kitted out Mac Plus... which as a mid 80s baby, by the time I had it in the early 90s, it was a little long in the tooth. As at school we had LC's, LCII, III's, etc... But, I was able to utilize SO much of the LC software, and my own, back and forth... that it really gave me an appreciation for the early apple / mac ecosystem. I enjoyed the heck out of it really, and my dad was the one who made it all possible... as at the time he did his own painting and remodeling thing, and being that I was into electronics and computers, he (unbeknownst to me) took on a job where a good portion of the payment was in trade, and that trade was the Mac Plus, external SCSI HDD, multiple external apple FDD's, and just boxes and boxes and boxes (all og boxes no less) of software. And I mean original apple hardware boxes for the computer, the image writer (original, later got an image writer II from school due to friendly relationships with staff), the HDD, and all of the other hardware accessories... as well as all of the hundreds of original boxes for the, well, basically every single piece of software ever written for the early Mac ecosystem. The guy my dad did the job for, who traded the computer and software for the work, he was some inventor.. who held patents for the original miracle ear, some derivative of space food, laser blocking license plate covers so laser speed detectors couldn't see you... and a bunch more. And he used the mac plus it seems, to develop a lot of this stuff. From cad titles, to print and design, to software development, to games.... as all these types did for sure enjoy a good computer game back then, and there were cases of disks that were nothing but. But all of the spiral bound books for the hardware and software alone would bring a fortune today. And of course, not seeing what it was worth, and after getting my first "actual computer" in 97 (Packard Bell 233MMX), I actually did the unthinkable and gave it all away. Ever since I've been piecing back together bits and pieces of tech I had as a kid... but the mac plus still eludes me. They are often around, with saved searches and listings, even locally, usually being a thing that exists... but I've honestly found it easier to just grab all of the other items in whatever condition they happen to be in, fixing them up, stowing them away... stockpiling my old tech collection. But the mac plus... every one that I see for sale, they all fall short somehow. This one that I had, it was so complete... I just know that I'll never have that again. So I just never pull the trigger, and haven't even tried. BUT... seeing this... man. I didn't have any idea this was even possible! All of the things I'd done with mine over the years, and all of the hardware I had... but I NEVER knew it could do this!
Back in the '90s common Windows X86 computers could do a second monitor, but to your point they were not graphical, only raster. I set up a second monitor on my boss's computer that would run under Borland's C++ development environment that allowed him to see debug information real time while developing Windows code. It was just a raster system and we had an extra monitor lying around so I bodged it up for him one day when he was out and he loved it.
I love it that you take us through all the processes and all the discoveries, faults and happy moments as well. When something turns out to be working I too feel the satisfaction and joy of your work :)
This is really exciting stuff!
Very much enjoyed this video, Adrian -- including your never-ending effervescence for this seminal tech. It also speaks volumes about how forward-thinking the original Mac team were. Andy Herzfeld (Mac OS) and Burrel Smith (Mac hardware) not only founded Radius to realise the full potential of the Mac's system software, but Andy and Bill Atkinson (Mac graphics guru and MacPaint author) also founded General Magic, the very first "iPhone"-like PDA.
