So I was gonna do a whole big thing, but I've had little time, so I figured I would throw a few pics up. Tested a ton of RAM and a few HDs and CDs/DVDs.

And then there's a brace of these:

They don't power up, but I haven't had time to take them down and check. Missing a few minor bits but nothing apparently critical. One has a very small crack on the screen, so I don't know what to do about that yet.

On the other hand, this works:

AST Pentium 133 from the "funky proprietary backplane design" era, in this case apparently not to make the case smaller, but just because, hey, backplanes! CPU is good, RAM is good, replaced optical drive, was missing PSU and I have to get a switch that works properly with this case. Has built-in S3 Trio64 V+ "Turbo," Turbo apparently meaning "with less RAM" in this context. I even found out that if you go back to Hiren's boot CD version 5.0, it will boot on these 90s machines.

Seriously, this case was designed by a maniac. It's got more interdependent parts in its assembly than a Volvo. Easy 9-step processes everywhere! I'll get more detailed pics later.

I'm also glad I got a picture of this label before I found out that it's basically watercolor (or early inkjet printed on plastic film), because one swipe while cleaning wiped half of this out and it was gone.

So a reminder that just because it looks solid and it lasted 25 years doesn't mean it *is* solid. Also it was apparently never cleaned before.

Miraculously, drive rails were included, and this is my first attempt at reproducing them. I chose a 2-part design because of the shape of it, and the fact that the "arm" has to bend. I planned on using screws, and still might, but on looking at it I could probably print a pin and use it to reinforce superglue - I wasn't confident that just superglue on the flat surfaces would work that great.

I didn't get pictures yet, but I got an Athlon XP-based HP as well. Had planned to do something else today, but here I am playing with my train set.

Attempted to fix the CFW on my PSP-2001 and it decided to not boot anymore and the display is a mess (got it cleaned off internally, but I'm not sure if it works due to the system not working ATM).

Heh yeah, AST sneered at the clone makers back in the day, saying "The best technology they've got is a screwdriver" meaning they just used standard parts and screwed them together. So I guess they were out to prove they had 10 screwdrivers for every one the competition had 🤣 But yeah, designed and made their own platforms basically. They did seem to integrate stuff well and their machines tended towards faster and smoother than contemporary machines of same spec. But Holy. Freaking. Screws. though, assemblies needed assemblies to fit them to other assemblies, brackets and lugs were not part of these and were screwed on separately, and brackets had sub-brackets. It's almost like AST was originally a small metal pressings company and just requested manufacturers send them "some kind of motherboad" "some kind of PSU" etc then they fitted together all what they got with eleventy one little bits of metal. Back in the day, I got an AST 386 with a burned board, and due to repair/replacement being uneconomical as it was obsolete, you weren't randomly gonna come across anything that had a hope of fitting, I stripped the thing out entirely. I think I got a full cup measure of screws and small hardware out of it.

I would detach the acrylic plate before retrobrightning. I ruined one like this - it got some very minor cracks all over it's surface - like a spiderweb. Unless it's not an acrylic plate over the space the display should be?

There is not one. The LCD display has its own that fits directly into that hole 😀

Yeah if part of it goes bad, it's kind of a loss. 😒 But fingers crossed.

I guess we'll see if that "faster and smoother" thing has any weight when I use it as a test platform for late-era DOS / early Windows benchmarking of my hardware from that era (mainly video cards). Eventually...

IIRC this chipset can do P60 to P233, and I have both, so that should be interesting as well. I have not tested this with this particular motherboard yet. I also need to fabricate a better CPU cooler for it, the airflow is not great for such a customized case (it has a small distribution fan between he upper and lower sections). I may do something about that airflow, or maybe I'm just always looking for an excuse to 3D print something, especially ducts for 120mm fans. 😀

Oh, and I fixed three keyboards today. The old IBM (membrane) was just in need of cleaning, the old Dell had some detritus stuck under the membrane that was making the zero key go off by itself, and the mechanical keyboard, which was newer, needed a new switch soldered on.

Installing Lubuntu 10.10 on my AMDk6-2 400 rig with 256megs of ram. Why? Because I bloody well can.....😉

Just out of curiosity: what do you use an old Linux distro for? I understand using old Windows for games, but what can you run on an old Linux that you can't on a new one? honest question.

For running old (binary only) software and the nostalgia of it, I suppose.
Library dependencies, binary formats, etc. makes it difficult to run old programs on a new system.

I'm troubleshooting an AOpen Vi9 motherboard that is kind of curious and important to me because it's a 386/486 combo board with VLB. It doesn't POST though. There is some battery damage I am fixing up, but I also noticed this strange solderjob on the chipset legs, it's as if two legs are soledered to a joint solderpad that go to the same via. Anyone think this is leftover from a botched repair attempt (and possibly root of the problem) or just something normal? Maybe they are both ground or something? I am not familiar with the chipset in question but the markings say it is an EFAR EC798.

I can't find a datasheet for it, but it looks ok to me. The PCB trace looks to head for both of the pads, so must be meant to connect to both pins. It's also looks slightly thicker than the nearby traces so might be a ground or power connection, or a configuration pin.

OTOH, a thread here https://www.vcfed.org/forum/forum/genres/late … v3486ef-386-486 has a photo of the same chipset with those two pins with separate traces.

How is Arch going for ya? Figured it out yet?

Few days ago I retrobrited a VGA monitor

Looks like the legs share a soldering surface and a route, so it's probably not a defect.

That's weird, I see 997 pages.

Need to plot out my "final collection," holes and all, later today. If I have time. Part of my problem is a lot of what I will likely keep are "cool surprises" and not part of a plan. Complications.

And I got my systems and video cards laid out (on paper) by year (short a few video cards in systems). Sound cards next, then a "what I need" list for controllers and NICs and what-have-you.

And if I'm very, very lucky I will get to moving some drives off the shelf into systems, clear up a little space.
