A repair attempt on the non working motherboard will come out in a few days on the main channel, so you don't have to wait long! It's going to require quite a deep dive. I won't say more! 🙂
Thanks for an amazing review. We will adjust the design to work better on the SE. On bench I use a standard atx power cable extension so the compact card is not plugged directly into the board. This gives me full freedom to probe anything on the logic board. Also the compact board has test points on it and they are labeled. -5v is used by the 26LS30 chips for serial and printer usage.
@@MartinaDyes a custom one can work but atx psu extension cables are already made with male/female and work just as good. See some my videos you see the yellow cable I use attached to it and the logic board. I could cut the extra plastic off nicely to make it look better. Think the cable was like $10 from Amazon.
An extension cable was my first thought as well, glad to know a simple off the shelf ATX cable works, even if there's extra unused pins hanging off the side. Great for troubleshooting or mounting elsewhere in a custom case. Better than talk of modifying a board to relocate speaker or floppy connectors, unless you really have a space crunch.
Adrian, ThisDoesNotCompute (Collin) already figured out that a normal ATX extender cable can be used for this purpose and diagnose the motherboard without having too much cable around! Cheers, I love your videos, they're entertaining to watch and you're smart.
I enjoy watching you troubleshoot the Macs, because I have a few Macs with that style of motherboard, and although they are running, just watching your troubleshooting technique, is very helpful to me.
Well back when I did stage lights for community theater we used to use a combination of steel blue gel sheets from one angle and bastard amber from the other to illuminate the stage, the combination in conjunction with standard pancake makeup made the actors "presentable". So if you added a bit of amber to your basement you might get a rousing encore from all your fans!
I am the one who gave you the watch cam. I did send you the photo in a patreon message. I am not sure where to find your email in there. I know I saw it before. Wish we had had more time to talk about it at the show. It was a crazy busy weekend I know. The guy I got that from actually owned a security business and used them to aim the old CCTV cameras in the field. Seems like it was a handy way to do that. He had 2 and I should have grabbed the second one as well... Thank you for all that you do for the hobby and keeping interesting history alive! Joe.
Ah yes. For the email, just go to the channel page www.youtube.com/@adriansdigitalbasement2 and click the more link near the text up at the top. Then it exposes socials and an email address. I don't know why UA-cam burred it! As for the watchcam, yeah that's a really good use, especially back in the day before we had all these fancy IP based cameras 🙂
I said this before and I'll say it again. You need the gamer's nexus mod matt. It's mostly black. It's super durable. It can resist soldering damage. It's ESD safe. And it has some useful diagrams on it.
Back in the day, I actually had the smaller Sony Watchman, along with the external C-Battery Power Pack, Rechargeable Batteries, Stereo Headphones, & a DC Adapter for the car. At 10 years old, I saved monies from my Birthday, Christmas, & Chores to purchase the Sony Watchman, from Pranges, for $150. It was probably my most expensive 'toy' at the time, but it was great, especially on long road trips, where the scenery consisted of corn & soybeans, for literally hours. Back then, we didn't have a VCR at home, so it was a good way to see a show all the way through, & not miss anything, when mom or dad said it was time to head out. I still have it in my collection, along with a Mega Watchman Boom Box, & TV/Radio combination. I may bring them to VCFMW20 in 2025, to demonstrate & sell. As always, nice review, & your videos are never too long. :)
If he just stopped blabbering and concentrated properly on what he is doing, he wouldn't make mistakes. shut up and slow down. He has make other mistakes before as well. Putting DIP ICs in backwards for example.
That WatchCam monitor would certainly have been very handy for installing analogue CCTV cameras, back when equipment was a lot simpler (versus today where setting up an IP camera needs more than just a little pocket telly to set up!!), making it easier to aim a camera when up a ladder before locking it in place and finalising the connections... :)
@@eDoc2020 Not much intuition really, analogue security cameras typically had BNC connectors for their video output, and a portable "WatchCam" branded monitor like that with BNC input, easy to deduce its' official purpose, after all, it'd be too small to realistically use as a security monitor, and its' size is perfect for carrying up a ladder safely... :)
I think Adrian needs a new shirt for VCF SW (next year). On the front, it would say, “I think it’s getting hot!” And below that, a depiction of an IC with flames coming out. On the back, it would say, “Ya think??” and below, a picture of a burn mark with only the IC pins left over. 😅 I’d buy one!
The power/video connector on the SE/30 motherboard is physically just "half" of an atx connector. The pin keying matches one side. If you have an ATX extension (easy to find amazon) you can use that to extend that connector.
@@rivimey I was talking about the camera which came with that monitor. And the TV you're referring to is the FTV-1 which used a rather unique flat electrostatic deflection CRT.
The SE and SE30 use standard ATX pinout (20pin) so a simple extension cable will give you access to everything - you can also use it with an actual Macintosh! Amazing tool for the Mac, I might get one myself so not to have the 10kV around ;)
Blue, not a fan. Shadows make you look unwell. Maybe if you put a piece of clear plexi under your bench light at an angle to reflect some light to fill in your face?
The watcham probably has no accessible brightness control to be consistent for viewing between recordings. As someone else posted the circular protrusions on the case might be a coin twist style open point
I’ve just come from nostalgia nerd’s update on the “checkmate” monitor. I seriously think Adrian should get one! No more rgb2hdmi/scaler/capture woes. Please Adrian check out the project i think you’d love it!
Adrian's Digital Basement "It fixed itself™" + MJD's "Of course we're gonna have problems..." Would be like strapping buttered toast to a cat and dropping them on the floor. You could probably do a video with those two guys and something would either explode or you could power a whole city, at least till the video ends.
For the Mac SE motherboard, you could always plug the floppy cable in before installing the power supply adapter. The cables should bend enough to clear the other board...
while the power board is cool plugging into the board directly in a permanent install, for this kind of testing it might be more useful to have it on some kind of extension cable? it would help with the speaker connection as well as allow better access to the board for troubleshooting
It's amazing how someone created a power source with a pico. What's crazier is that with such a processor in that little component, the power source is a WAY more powerful computer than the device it's powering up.
There are not enough decoupling caps on these boards. Fixing itself is the electrolyte caps self-healing after deteriorating from disuse and bringing the system just back into spec.
24:00 Yeah, direct light such as a ring light will be pretty harsh and difficult for you to see. A 150w or higher watt bowens mount studio light, light stand, and a large bowens mount softbox. At least depending on the space available. The bigger the better, and generally, the closer the better. Or you can get a large 5-n-1 reflector with a light stand and reflector clamp. You can shine light through the inner white diffusion part, or reflect the lights off of the silver/white side depending on what the reflector offers. Depending on the lights used this will be a cheaper option and hopefully shouldn't blind you compared to a non-modified ring light.
As far as you being able to use that power supply and being able to work on it at the same time. You could always solder on the correct harness from a non working system directly to the board and still be able to do the testing. I can't remember if it uses a harness from the power supply or if it plugs directly into the power supply normally from the actual computer.
I wish I owned my childhood Motherboards We had a Tandy 1000 SX and a Pentium 1 and Long after we had the P1 I got to have the Tandy 1000 in my bedroom and I did lots of Things you can do with Dos 3.2 on it when you have 389k ram and only 2 5.25" Disk drives.
If you want to use that diagnostic board on the SE or SE/30 and not have the board blocked, just remove the connector and solder on a wire pigtail with the MiniFit Jr. crimp connector. If you have a sacrificial power cable from a SE, you can chop one end off and solder it on. If not, you can still buy that 14(?) pin connector on Mouser. I'd love to have one of those boards myself to help diagnose a wonky SE motherboard, but holy hell not for $140.
Re: lighting: Maybe a string of holiday lights near your workbench? Something near yellow or orange would counteract the blue, but then your face would change color a bit if you leaned forward.
Modify an ATX power extension cable to fit the SE motherboard and set that adapter board off to the side so it's out of the way. Much easier for troubleshooting.
Given the physical layout of the CRTs on the Watman units, it would be surprising if they had good geometry. Even high-quality, professional CRT displays were often victims of bad geometry. The first movie to make major use of CGI, TRON, had some big problems with geometry of the monitors they used to transfer the CGI to film. The first pass of the climactic battle had the characters all over the place on the CGI background. They had to manually fiddle the whole sequence to et it so nobody had their feet landing on empty space.
I'm wondering if there's an impedance issue with that custom video lead for the WatchCam? Might be dragging down the input pk-pk voltage and making it dim??
You could make an extension cable for the se motherboard plug using the connectors from the junk bin, then that cool piboard can sit to the side of what you're working on no matter what you plug it into.
56:58 To me, on the the Sony WatchCam, it looks like the two plastic 'crescent moon' shapes on the right hand side just by the orange Sony sticker is a classic 'coin twist' opener to unclip the front panel - could the controls be hidden under there? Otherwise, why have those 2 lugs on the case?
Put a gel in front of the bench light that tints it orange or amber, to compensate for the blue maybe? Alternatively if you add a front light, tey something fairly dim at first, from more above than straight ahead (because you're looking down and it won't be so much in your eyes). There probably wasn't that much light coming off the bench, it might not take that much to add that fill you're looking for...
that sharp crt reminded me of my little 5 inch crt which has some leaky caps and probably some broken solder joints if i could send it to you for a repair and review video of sorts id love to (as long as i get it back since i do like to use it with retro consoles like my ps1 and snes)
the Watchman wa widely used in the earlu mid 90's on movie sets when wireless videotaps on film cameras became available, everyone wanted to see what the camera was filming and the4 fact that yours has a bnc input tells me that it was probably where it cames from
@adriansdigitalbasement2 The issues on the SE/30’s really look more like corrupted PRAM - anytime you make any hardware changes like video output or SCSI devices it’s always a good idea to zap your PRAM a few times.
I'd also check around to see if cap juice is affecting the PALs and other support chips/muxxes. Something is definitely holding the reset enabled when it shouldn't.
6:17 The Classic II was never meant to be a successor to the SE/30. It had a 16-bits bus like the LC (SE/30 was full 32) and indeed no FPU. It was more meant to be a successor to Classic which was a reduced cost update to the SE.
lol that's a key shaped burn, stain or something that's been part of the bench since forever. For the longest time I thought like you it was something sitting on the bench, but considering it's never moved at all over all the bench vids, it's got to be a shadow stain or burn. That said, RIP key shadow burn! While the blue anti-stat mat looks sexy, it also means the end of our key shaped friend. End of an era that =D
@@xrror I remember watching through Adrian's old videos and coming across the TRS-80 video where that stain was created, it felt like I'd stumbled across Deep Lore.
You use your hands which is useful to you. It is my opinion that you need one of those fancy thermal cameras you see used - especially by people who troubleshoot and fix electronics. Hmm... Maybe it's time to send you a care package from Maine. I haven't heard you mention Maine during your mail call videos, so it'd be a first. Sadly, I'm not sure what to look for in a thermal camera. I have no idea what's good and what isn't. From a quick look on Amazon, some of them aren't all that expensive. Then there's the IR thermometers that have laser pointers built in. Those are cheap.
I got a USB-C connected camera for my android phone TOPDON TC01 which works absolutely fine. Then it was something like £150 but is now more. I agree that the finger test can be a bit low-resolution and that a device like this would help viewers understand better as well.
@@rivimey I think it'd be a good tool for him to add to his kit. I'm a wee bit surprised that he doesn't already have one and use it. Real numbers are better than 'this feels hot', especially for us viewers. I took a look at the option you mentioned and it looks like a solid bit of kit. However, it's USB - which means it needs a computer. Of course, that's going to be a requirement for him anyhow - but something a bit less tethered would likely be ideal.
I had a Mac Classic II. I tried to get it to boot with Mac OS 6 (something) and I remember getting the error message that it couldn't boot OS 6. I would have never thought that you could get around that by using the programmer's switch on the side. Wow!

Rewound a couple times, you definitely did not swap the ROM SIMM but grabbed the exact same one.
at 26:45 you put down and picked up the very same ROM SIMM, Adrian.....;-) The next board didn't get no DeOxit on it's slot.

How about an Mac SE power cable extension to get your card out of the way when working on the bench like here?
@@MartinaD the se or se30 power cable has both ends as male and won’t work.

Andrian, you mixed up the ROM Sticks and tested the same ROM Twice. (around 26 minutes)
It's amazing how someone created a power source with a pico. What's crazier is that with such a processor in that little component, the power source is a WAY more powerful computer than the device it's powering up.
I have a recapped SE/30 in an SE chassis, and it does that same thing when it's been sitting for a while. It always boots on the second attempt.
There are not enough decoupling caps on these boards. Fixing itself is the electrolyte caps self-healing after deteriorating from disuse and bringing the system just back into spec.

Where do I buy Pico ATX? I see several vendors, unclear if they are all the same or have the same output.
Excellent debugging by randomly pressing and pushing components - I hope I get so lucky on my next find!
burning hot ICs equal bus contention!
as for the mat lighting issue, just be glad it was not a red mat, you'd have to admit to being a Sith Lord :p
The SE/30 was basically a portable Macintosh II.
Portable IIx, the Macintosh II had a 68020 processor both the IIx and SE 30 were 68030
ah, what have you done! now the iconic key-like imprint is gone! just kidding, i love your videos! - keep up the greats stuff adrian!
I've always wondered, what WAS that imprint from? 😄
@@ricdeckardI think someone hinted to a TRS-80 video in another comment thread.
Cool!
A breakout/extended harness wouldn’t be terribly difficult to fab
What would happen if you focus a red light on the blue mat? 🤷🏻🤷🏻
Your desk glows blue. There must be bugs nearby.
"color balance" has many technical connotations and uses, try the balance of color is off with the blue mat. 😅
You use your hands which is useful to you. It is my opinion that you need one of those fancy thermal cameras you see used - especially by people who troubleshoot and fix electronics.
Hmm... Maybe it's time to send you a care package from Maine. I haven't heard you mention Maine during your mail call videos, so it'd be a first. Sadly, I'm not sure what to look for in a thermal camera. I have no idea what's good and what isn't. From a quick look on Amazon, some of them aren't all that expensive. Then there's the IR thermometers that have laser pointers built in. Those are cheap.
I got a USB-C connected camera for my android phone TOPDON TC01 which works absolutely fine. Then it was something like £150 but is now more.
I agree that the finger test can be a bit low-resolution and that a device like this would help viewers understand better as well.
@@rivimey I think it'd be a good tool for him to add to his kit. I'm a wee bit surprised that he doesn't already have one and use it.
Real numbers are better than 'this feels hot', especially for us viewers.
I took a look at the option you mentioned and it looks like a solid bit of kit. However, it's USB - which means it needs a computer.
Of course, that's going to be a requirement for him anyhow - but something a bit less tethered would likely be ideal.
Change white balance of camera to a warmer color
Why didn't you degauss the Sony monitor? Do you not have a degaussing tool?
I had a Mac Classic II. I tried to get it to boot with Mac OS 6 (something) and I remember getting the error message that it couldn't boot OS 6. I would have never thought that you could get around that by using the programmer's switch on the side. Wow!
@CathodeRayDude will know what it's for, the monitor

i still have my Sony Watchmen FD-42E and the CRT is much bigger.
I'd love one of those desktop cases for the SE/30!
Me too! I'd love to desktop-ize an extra SE/30 mobo I have
I think that's the new future for Macs like that; ditch the analog half and keep the digital half.

videos like this are why im subbed to adrian 🙂
Yelling at screen: "you put the same ROM simm back in".
👍🏻
Can you imagine CRT mobile phones? Pretty sure someone at Sony could…
We might get application of the current tracer? Yeah, I was waiting for that to happen!
Degauss?
