I see a lot of memories on that tree.
Rammy has a new punny friend. :)
@@yakskiis7426 Just don't unplug it or the memories will be lost.
A lot of old memories.
@@kenkobra - unless you spray it with liquid nitrogen first... then you’ve got a few minutes. 😉
I forget
Always an adventure diving into machines like these! Thank goodness the battery didn’t yet go all 2020 onto the motherboard and ruin it. And I just love that funky CD tray.
Nice impression too 😄
I was actually confused for a moment :D
I don't know about pro audio thunder, but a true pro audio spectrum sounds much better than a sb16. I had one back in the day and I replaced with an awe 32 or an awe 64, I don't remember which, but I was disappointed in the replacement. The PAS had great sound in the games I ran.
I also had that same exact CD rom drive. Man that thing is SLOW.
That memory tree is the best part of DOSC:\ember
posible 2x2mb & 2x1mb but the bad mem test is coz the clock is set at 50mhz
It's also nice to see Rami moving around. That means she is a dynamic ram, not a static ram! Baaaa haaa haaa! I'll show myself out now... ;)

@@minty_Joe Ahhh it's 73 not 73s! Such a pet peeve of mine. 73 from a mysterious VA3...
I looked up that FCC ID, and sure enough, they got this computer certified in 1993. That's some dedication.
...and that company is still in business in Oregon!
Might have been a requirement for some government customers.
back when folks were still concerned about fed gov't enforcement...
@@rillloudmother They are still concerned, if your last name is Trump.
He’s not the one who added 80,000 IRS agents to the payroll, douche.
leaving a USB floppy attached to your Windows 10 machine and rebooting to a 'non-system disk or disk error' is just accidental retrocomputing
Windows really is just a jenga tower
Christmas tree needs an Energy Star on top :D
You win this comment section.
By the extra set of socket holes around the processor, you can see that this board would also accept an Intel Overdrive
In 1993 some friends of mine and I started a computer company -- we'd build and sell computers using off-the-shelf parts. This video brings back LOTS of memories for me. I honestly do not know how many of these exact computers I built and sold in 1993 and 1994. Dozens and dozens and dozens. This generic mid-tower case, the generic Winbond I/O card, the generic VL-bus-equipped 486 motherboard, the generic 30-pin RAM, etc., etc., etc... So many memories! Very cool to see this machine still working after all these years. :-)
In the 90s, the *cover* was the cable management technique of choice. :)
22:45 I remember being bedridden with something similar to measles when my Grandfather broke the news to me that he'd managed to break the motherboard of a PC we'd been working on. "I connected the power supply connectors to it the wrong way round". "Ah." I nodded sagely, confident in the finality of its demise.
Theoretically, those little pins on the connectors are supposed to stop you from putting the connectors in wrong. Apparently on this mbd, they didn't clip the openings so the connectors would slide in straight. Unfortunately, they can be put in with a little tilt to get around that protection... :)
@ 1:45 - great Clint Basinger impression :D
(1:54)
"Black to black's got your back" is the saying that I remember...
I've always said "Black to back or you'll never go back"
I've always used "Red to red, you're dead"
I've blown *one* motherboard because I didn't know what I was doing...
I always use : "Red on red, tou're dead, Black on black you're back"
@@TheotanyaSama No, if you power it up with red to red, the motherboard's dead, and no amount of black on black will bring it back.
I just remembered it by saying that "blacks are supposed to stick together." Never blew a motherboard in the AT era by messing that up, what little time there was of it for me. (94-97 then ATX pretty much took over). The next motherboard I recall ruining wasn't until LGA 775 (screwed up the socket pins somehow).
Nice LGR impression 😎
I did notice that the clock speed had gone back to 50mhz in the BIOS again. Vaguely remember that odd multiplier's caused issues with the IRQ for the less popular sound cards?
Could explain the pitches being wrong in the PC Beeper music too. Worth a look-in, as well as possibly checking the filter caps. An ESR meter would do him well, as some caps fail without leaking, they just dry up. Others are totally fine and would be possibly a downgrade to replace if they're not measured.
The mix of cards could introduce irq conflict, also if ram is of different speed rating could effect program speed. Try checking if turbo jumper not closed - this may return bios control of setting.
PS - removed bios battery...🤔🙄😆
That CPU would most likely overheat and crash pretty quickly if it ran at 50MHz, so I doubt that setting actually changed the FSB. EDIT: Unless it actually set the FSB to 25MHz, that's possible.
Ohh god the old cases, giving me ptsd of slicing open my fingers/hands
The metal standoffs for the motherboard have another purpose. They ground the motherboard to the chassis.
IIRC, there was an initialization program to run, for SB compatibility to work. I know that once I had everything set up right, my PAS16 worked for any SoundBlaster program I threw at it.
Finally a video about mini-tower. I had a Pentium 166 MMX in exact same case many years ago.
22:28 "Read to Red, you'll always be dead, Black to Black, you're safe Jack"
but what if i'm not called Jack?
I just realised that Doomguy wears gloves! I always thought he just had some weird wrinkly hands... 2020 just keeps getting weirder.
ED was extended density. They were more common on IBM PS/2 models and capped out at 2.88mb.
The drives might be common on those systems, but the disks? I've never seen ED floppies.
@@mrnmrn1 I used to volunteer for a nonprofit that recycled e-waste and I only came across a 2mb diskette once. My family used to have a whole box of the ls120 ones, though.
@@richardestes6499 2-megabyte 3.5" disks are just HD disks. Their basic capacity is 2 MB, but formatting takes a chunk of the space for the file structure. In case of the FAT12 used on PC, the usable capacity is 1.44 MB. On some other systems, it would be different. (If I remember correctly, Macs of the time used their own formatting.) In the early 90's the non-formatted disks were a little cheaper, and they would be typically labelled as 2 MB (or the DD's as 1 MB). Later it became standard for the disks be factory formatted for PC -- but if you needed them for non-PC system, you'd just format them on the system, just like you would do in case of non-formatted disks.
I've never seen the 2.88 MB disks, but I'd suppose their non-formatted capacity would be 4 MB.
@@enginerd80 And, there were utilities to format them to higher capacities by utilizing more tracks. Hit or miss on reliability depending on the drive as well as the physical disks used.
That's the exact cabinet of my very first PC. A Cyrix 486 DX 4MB RAM, 540 MB HD. The small display has a glowing green color for CPU speed... 88 to 100 on turbo or something like that. A very lovely present from my mother.
Remember him saying in one of his early videos that he normally wasn't one of the retro guys? Now he's making christmas trees out of memory modules xDD
We've corrupted him
@@kaitlyn__L but hopefully we haven't corrupted his memory! lol
That's exactly how I remember PC's in the early 90's. Those all seem like typical problems we all encountered.
I had a Mac in this era -- a Centris 650 -- and it just worked, elegantly and beautifully.
@@iocat Yup. I was still primarily an Amiga user at the time. Same story. Those just worked.
Fun thing about dialup is my ISP still supplies an "emergency phone number" for dialup when the broadband craps out, but when the broadband crapped out for me a couple months back, the phoneline itself was failing so dialup wouldn't have even worked anyway!!! :P
the darkside of VoIP
i remember the early days of the CB demise - that channel 36 was used by wireless data testers - to link a 9600b and send files over CB
@@herauthon Here in the UK, the majority of our phonelines are still copper, so not VoIP just yet, but when there's corroded and broken wires, it doesn't matter either way, call and data are going nowhere... :P
@@twocvbloke
Well, we got Cable - and i assume it is a cupper connection - but the modem uses VoIP - to convert analogue phone signal to digital signal - effectively VoIP. [ ihmo ]
Juno still offers free dial up internet 🤣
A perfect example of what problems you had with PCs back in the time. You got a PC from someone and something didnt work. Three hours later fiddeling around with cables, cards, adresses and interrupts the thing worked perfectly fine. When the guy got around to pick up the PC and asked "What did you do to fix it?" you would normally answer "I have no idea".
"Black to black, no flack, red to red, you're dead" is the way I learned. Usually I've found that in most cases (I've tried, with power off and PSU discharged) it won't even let you plug it in red to red, those little hooks never let it fit.
These old 486 systems in a non-descript box, with that purple, orange, and green BIOS, oh man those systems were HORRIBLE! Just like the weird issues you kept having that would pop up and seemingly go away, that's how these things ran. Quirky at best. Some days good, some days bad.
The way it used to be, with those multi-I/O cards, a million jumpers, and no documentation, endless reboots and running test programs to make sure you had no conflicts, drove a lot of techs back then to drink. I'd love to finish that with "ask me how I know", but fortunately I can say I wasn't old enough to drink then!
I used to have a 486DX50 around, sound card, Ethernet, and had some sort of proprietary Sony CD-ROM drive that hooked to the Sound Blaster card's Sony connector. Even added the drivers to the Windows 98 boot disk back then for it. And the MicroSolutions BackPack parallel port connected CD-ROM drive. I actually have seen the type of CD-ROM you had in this machine, that thing's a gem. I had an old 2X drive, it actually had a 1X/2X light on the front, and when it could achieve 2X speeds it would light up that light. Back when they made the hardware do something fun in and of its own right. I don't think anybody ever had a problem with more blinkenlights.
Great video, but I'm commenting solely to say that little ram plushie is pure, distilled adorable.
You paused the boot sequence the first time, maybe that’s why it said 6mb then 8mb on the reboot?
What a flashback Adrian! Thanks for doing this one, I'm only a couple minutes in and OF COURSE I remember this case, I built MANY system in that style case, and ours had the lcd number box.. We had metal badges for the square on the front.. man the days. I forgot the old red Intel inside sticker.. man it's been SO long..
48:56 The nice thing about Windows 3.x was that an incorrect video mode could be corrected directly from DOS. Running SETUP.EXE from the Windows directory was usually the preferred way for most people, while the SYSTEM.INI edits were the more hardcore way (and in some ways faster for those of us who did that enough.)
Absolutely loved this Adrian... Would love to see more like this. Happy Christmas and new year
2.88MB drives were used mainly in PS/2 and RS/6000/POWERstation systems.
Don't ditch that sound card as they tend to be pretty good to even desirable for collectors so maybe check the caps.
Agreed 🍩
I don’t think he ditches anything. The dead parts bin would agree with me in this
He has the wrong drivers.
HighTreason610 has some valid concerns regarding the SoundBlaster 16's audio quality vs the PAS16:
ua-cam.com/video/sdphd742Oqs/v-deo.html
I haven’t heard of this particular board, but I had a PAS16 back in the day and it was fine. It was an upgrade from an SBPro, before the SB16 was readily available, and came with a fancy MOD player that played in 16-bit stereo mixing.
My only complaint was that Wolf3D wasn’t in stereo, and maybe one or two other scene demos or something that could only use the Sound Blaster compatibility.
What I didn’t realize back then was that the SB compatibility was actually provided by a dedicated chip from the Thunder Board (an SB clone) and meant I could have used two wave devices in Windows - which would have been a pretty neat trick back then!
Anyway, it was a solid card, so I suspect the drivers aren’t working right or something here.
Oh, and the PC speaker thing - it actually listens to the IO address of the timer to intercept and emulate it.
I sold my first CTL computer in 1988, a 286. Computer Technology Link or CTL is still in Portland selling computers wholesale. The owner David Kim had me design some logos for him and the Big K with the im in the leg is the one he chose. I sold their computers even after I retired up until about 2010 when I retired again. For a time they made their motherboards in California using their own designs. I visited the plant once, it was pretty amazing. Their monitors were made in their own plant in Korea. I still have a pallet load of 17 & 21 inch monitors. They are good people to deal with if you are a computer reseller. Thanks for the video!
Seeing that machine brings back a lot of memories! Thank you for the video!
I had a "Thunder Board for Windows", Thunder Board was MediaVision's 8-bit Sound Blaster clone. It was a great pairing with my 33mhz 486DX. The "for Windows" variant just came with some Windows 3.x software (like the excellent Sound Forge 1.0!). I wasn't aware they used this Thunder branding on their PAS at some point in its lifespan!
Love these long form deep dives. Glad I came across this channel.
Merry Christmas Adrian! Thanks for all the hard work making videos this year! Looking forward to next year!
25:34 hahaha i burst out laughing! "there is a nice calendar there like if you're going to .. look at the calendar i guess? i always wondered why hat was in there exactly"
Man, I just love mini-towers. They're just such a perfect little squat compact PC, I think literally every school PC I ever used was a mini-tower, so many memories.
That blacks in the middle rule is one of those things that I can't remember where I learned it from, but it's ingrained in my memory like not touching a hot stove.
5:03 - Name-brand 80486 boxen usually came with an Intel Inside sticker. The ones we had in high school all had them.
Sorry I'm late to this party, lol. I had a 486DX-33 built by a company called Midwest Micro way back in 1994. It was a VESA local bus system. I was impressed by the speed at the time, with the local bus cards running at bus speed. The multi IO card died a couple of years in and I had to replace it with a 16 bit card, it just wasn't the same. My case was almost identical to this one, except it was a full tower and the display read 33. It was a damn fine machine.
Good job! I worked at a computer store in Yakima back in the 90s. Brought back some memories.
Case looks familiar to me too. I purchased many of these type of mini/midi tower cases back in the 1990s for various businesses I worked for.
This one looks like a great 486DX66 machine I used to use and was very proud of!
Also - some cases had sharp edges on the internal case metalwork. The times I skinned my knuckles getting a mobo out of a non-tray case!!
It says 486 in the FCC ID number so that's not a surprise.
Had fun watching this yesterday. Cool dude and thanks.
Consistently great content, Adrian. Looking forward to your 100,000 mark.
Merry Christmas Adrian from UK Stay Safe my friend. Brought back memories these PC Builds.
This was great. I love your videos. Happy New Year!!!
Your very lucky to have found that PC and gave it a home! Wish I had that luck finding an early 90's pc....
Have you ever tried Xtree Gold file management software, was a great DOS utility and I used in to about 2000.
Watching this video takes me back to my early days of PC, my first PC was a 386, it's great to tinker around with old computers but by goodness thankfully things have moved on in the real world and the average person can achieve amazing things with a modern PC.
This series is terrific. Definitely head to the recycler again sir, I could watch these old computers get worked on all day!
I have 30 in the garage to work my way through !!
@@highpath4776 Film it and post it, I'll watch.
So many memories in this video. Thanks! Love the Tomte/Nisse too. Very Christmas :-)
These old PCs live on to this day in machine shops. Mills and lathes that have been converted to CNC are frequently based on PC motherboards like this. Also I remember using outdated units just like this one to “DNC” programs to milling centers where the CAD/CAM generated program was too large for the machine’s internal memory. 7200 baud rate via rs-232 that sometimes required re-soldering the pin-out to get everyone to shake hands. Good times.
My cousin's family got their first PC one christmas in the early 90s after using their Apple //e for a few years. It was one of the first multimedia PCs we had ever used, and came with an encyclopedia on CD. I later found out it was a 486SX(?) running at 25MHz. Only a few years later I got my own Dell 486DX2/66 as a high school graduation present, although it was probably the last 486 model Dell ever sold since Pentium machines were starting to dominate catalogs.
Great little machine, takes me back to some of my first builds!
fantastic! I love watching you save old tech
I like so much the level of detail you put in your videos like FCC serial number, ROM flashing or technology in general, and it's not overwhelming it's enlightening, cuz my computer is new and nice, but i watch this videos to connect to the past era of computers, so again every detail matters, and thank you very much going trough every detail, that makes the window to the past more transparent, effectively bringing the magic of that era to live again today, thanks for your work aka magia!
O, and the logo on the front; to me it looks like Kim. Capital K and 'im' in small print in the leg of the K. Maybe the machine was owned by someone called Kim?
Exactly, take a look here: en.wikipedia.org/wiki/CTL_(company)
I was wondering if I was just imagining that, when he called it "K Inc". It's definitely a personalised "Kim" badge.
Wow that took me back! thank you great video as always
"what is it?"
"a memorytree"
"what DOS it?"
"holding memories ._."
Sweet, enjoyed that. :)
Brings back a lot of memories. I used to work at a small PC manufacturer in the early 90s, and this is very similar to what we made. That case is one of the very common ones, I remember every nook and cranny of it. Sadly I've forgotten who made it, but it was very cheap (around $25) and simple to build in. That motherboard tray was a real god-send and the primary reason we used it. Saves SO much time. We used to unhook the trays from all the cases in storage, and mount them as orders came in. Fun times.
As for the white bar with that Cirrus card.. I've seen that before, but can't for the life of me remember why it's doing that. If you find a fix for it, let us know eh? :)
We used several different Cirrus cards, they were really cheap back then, and mostly did the job. I seem to recall there were driver issues with them, though. Later on we moved to ATI cards, which were much nicer in general.
Happy new year Adrian, looking forwards to whatever you'll come up with in the new year. :)
Cute RAM tree. Although, from the amount you have been sent, I think you need more of them! Interesting video as always.
I was waiting for this particular video!!! i got the same case with a 486DX2 and still works! Nice RAM Tree XD
Looking up the FCC ID, it looks like there was also a mid-tower version of this ("CTL486MD"), a full tower ("CTL486FT"), and a desktop ("CTL486DT"), and then they made a Pentium-based one in 1995 ("CTL586PFT" and "CTL586PMID").
Yeah, I think Adrian gets confused with FCC REG at 9:18, because the ID is on nearly every piece of computer equipment.
I love the memory tree :D I recall struggling to plug in VESA cards on my 486-33SX (?) machine I had, you really had to push hard and I was always half expecting to hear a "crack!" and have it break in half! My father and I used to haunt computer fairs and picked up lots of cheap sound cards in that era, and always struggled with them to get them to work with all the games. I think in 94 or shortly after Creative came out with a new card (the AWE 32?) and there were a lot of SB 16 cards being sold second hand for very little, so we got a load for all our computers (I had 3, my dad had 4 including the one he "maintained" for my sister) and never had problems. When I bought my new shiny pentium 100 machine in '96 I bought an AWE64 and was blown away by its sound. So I was a big fan of creative... these days I use laptops and so have to use whatever the manufacturer supplies, but then again most game sounds these days are wave based and sythesis is something of a relic now.
I built several mini-tower computers in the mid to late 1990s. This video is a nostalgic trip for me, but I'd never want to go back there.
How you attached the cr2032 with a diode was the part I wanted to see most. Anyway, another great video.
He's shown it in earlier videos, but it's basically just a bit of solder and heat shrink tubing anyway.
@@kaitlyn__L I have a need to do it on several machines and I realize it is easy but I want to get it correct and the diodes location and orientation is not obvious to me as it seems to be to many.
That kind of cdrom used to be the Mitsumi brand in my country. Thank you for the video!
This was a great tour of the seemingly endless compatibility problems that everyone building PC's had in the 90's and why so many people chose to open their wallets to buy Dell or some other brand name computer. Nothing sucked more than getting a new card and finding that your computer wouldn't boot with it plugged in, or getting a new game and finding that your sound card only partially worked with it but didn't have problems with any other games. I wasted hundreds of hours of my life on stuff like this.
I have hate-love relationship with mini towers of early 90ties. My first two PCs 386 and 486 had them so I have nostalgia love for them but this was era when I changed a lot in them and cheapo towers where heavy stamped metal with lots of burr and sharp edges so in those tight spaces I lost a lot of blood fitting different drives, ISA and PCI cards, ram modules...
Yep. Building a computer back then meant walking away looking like you danced with Freddy Kruger.
It is a real FCC ID if you look it up. That is nuts.
awesome for saving more pc from being scaled
i always interested seeing u bring them back to life
Any one else remember having bleeding hands when messing about inside cases of this era??
I do remember having spaghetti cable runs as well... :)
Love the video's Adrian - Takes me back in time too to when I used to build my own computers....
Watching your videos is like being transporting back in time. You do a great job on the videos, and your knowledge is really vast, which makes watching fun. I kept my first computer which is now 39 years old, when I stored it away it was still working. Now Im going to dig it out and see if it will boot up. Panasonic Senior Partner, it was advertised as the first computer you can carry onto a plane. I remember it ran on DOS 1.0, and all that stuff was lost many many years ago. Hope I can find a copy. I worry about the battery, guess we will see.
I too worked in mom and pop computer stores beginning around 92-93 until about 99 building and repairing 100's if not 1000's of computers. This brings back so many memories for me and I'm amazed at how much I'd forgotten. Those plastic standoffs definitely belong on the trash heap of history along with the multi IO cards and their myriad of jumper settings that were never the same from card to card.
Thanks for sharing the tower.
How about, "Red to red, you're dead Fred. Black to black, you're on track Jack!"
A colour BIOS setup screen? Pure decadence. Back then when I were young we were lucky if we were greeted with a black and white BIOS setup. After a day down the mines, a solid beating from parents and gruel for supper it was a highlight of the day :-D
Great Video Happy New Year 2021
The 386 phone server with built-in amber CRT that I picked up at Computer Reset also had one of those barrel batteries that had just barely started leaking, so I'm glad I got it when I did and de-soldered it before any damage was done!
The RAM tree is freaking awesome! You need an LED star and it would be all set!
Someone else mentioned it needs an "energy star" LOL!!!
@@adriansdigitalbasement Hahahahaha I agree! It does need an Energy Star! :) Awesome!
Yessss! Thank you for making a video about this machine! I'm only 26 seconds in and already excited 😁
Ok, at 10:55, I am thinking it is a 486, using that Mitsumi interface for the 'crocodile CDROM drive' ( that's what me and a friend called it!), To a SB16-ish sound card. The rear audio ports suggest it isn't Creative... But I'm not sure.
The VGA will be a VLB card, slightly popped out of the socket.
The IO card will have an IDE and floppy controller, with the usual array of IO on it.
Nice video, and nice little machine - I hope you will do more PC videos in the future! :)
Remind me to watch this video every time I take SATA for granted. But I think the comedy of errors once its put together just captures the true experience of building a PC in the early 90s.
486s really were the gateway from the "old limited computer freak times" to the more modern "everybody uses PCs now" era :-)
Sooo much happened between the 286s and Pentiums.
I really love my 486-DX4-120 with Cirrus VLB VGA and 24MB EdoRAM. Even Duke Nukem 3D and Shadow Warrior (that came out in 1997 !!!) run very decently on it :-)
Only the CD ROM Drive is a single speed and a bit slow, but it came with the SoundBlaster PRO and I would like to keep it original :-)
It’s amazing how much time you can sink in to one retro PC just getting everything working perfectly - driver and irq and config file wise, even after you’ve selected the hardware you want and think will work, cleaned it and built it. And then there’s the software you install which is really what a computer is all about. Different things best or will work for each system, even for systems only a couple years apart. Good thing it’s just a fun hobby, I would go crazy trying to support a 30 year range of hardware and software in a business environment, a uniform modern fleet is enough trouble.
nice sound card! score! love these deep dive videos
Thank you for more archeology!
Always enjoy seeing classic machines like this being rescued 👍
In the 90's (1994) I used to have a 486 SX25 with a generic case with a round shape in the front. I overclocked it to 40 MHz, this was the time before regular OC. I didn't know what I did with jumpers, but it worked and I even installed a cooler with a fan. Now I bought a pentium 100 in an AT case like this one, it will do it until I find a case I used to have.
Merry Compu-Xmas! Nice TreeRam
I wish I had the skillset to make computer problems self solvable. Oh, well.... Another excellent, enjoyable, video
Man, that sure seems like an earlier VLB motherboard with the 30 pin SIMMS and replaceable crystal! Glad you saved this from being recycled!
Also, I believe I have used this utility to get HDD params from CF cards in the past: archive.org/details/msdos_IDEINF_shareware. Looks like that old motherboard don't have LBA support, I bet the BIOS will limit drives to 512MB
I remember, sometime in the mid-90's, I discovered the option to format a floppy at 2.88mb. I formatted several disks that way, it worked fine with most of my disks and all of the PCs I used them on. I never found anything that used it by default.
Anyone who scraps a vintage computer should be ashamed of themselves.
ohh merry christmas adrian
