Retro PC repairathon part 1: Triage

- Part 1 (of at least 2) of a retro PC repairathon. I've accumulated a bunch of these things over the last year, and it's about time to sort them out and do something with them! This first step is primarily triage... what's here, what works, and what future repairs are needed.
At least some of them will end up for sale at SideQuest Expo (www.sidequestexpo.com/) on March 9th and 10. Stop by and say hi!

IIRC the original IBM VGA card had one hole (pin 9?) plugged as mechanical key (to distinguish it from any other DE-15 connector), IIRC most clones left that off and even IBM soon dropped it but some early clones did do the same which I guess that explains the connector on B4 - Compaq was being REALLY compatible with IBM!. This pin and the similarly unused pin 15 much later got repurposed for DDC 2B (display data connection) so modern cables have them pinned, cables from that era did NOT. And both DVI and HDMI still use DDC 2B for EDID information! Even DisplayPort can talk DDC 2B if it supports "Dual-Mode" (IE DVI/HDMI over DisplayPort).
WEITEK FPU, that shit is rare and EXPENSIVE!!!! That is a JACKPOT indeed!!!!
Good stuff!
That first case is as 90's as a dude in a Mitsubishi VR4 wearing a Soup Dragon's T-Shirt. :)
Ha! I drove a Kia Sephia in the 90s, so I was for sure not that cool.
That’s a great comment! I do love that white case too!
Hey!! I had three cases of those collection. The first three that you pulled out! Green wave lived at my balcony till first Core I appeared. And I still have Am5x86 CPU and the motherboard from that build. The second case was a short lived one (Slot 1 Pentium III 800EB). I had that system for a year before upgrading to Pentium 4. And the smallest case had a Pentium 133Mhz (no MMX) with a very bad 1Mb integrated video card. I have donated it to someone in early 2000s
I like the sound that first one made. Also, I think I had a case like that one. It was considered stylish for clones to throw a piece of colored plastic to break up the beige.
Definitely interested in the repairings. I guess the last board supports 386+copro & 486 DX & 486 SX+copro... just waiting for you to unveil it. Gonna get some popcorn 🙂
I have a case similar to this one with blue detail with a SiS530 and K6-2 500 and a similar Soyo motherboard that needs recapping (sometimes it turns on and then freezes), in fact all the Soyo boards I've ever had suffer from the same problem . Great hunt!
About that plugged VGA pin. Early VGA connectors did have a pin plugged which was later put into use for signalling, so don’t be to hard on Compaq.
That's interesting. I did not know that. I have quite a few old VGA cards, and I don't think I've noticed any without all 15 holes.
That first one... I believe I've build many machines in that case. iirc I cut my fingers on those cases more than once. Could be mixing it up for a different cheap case we used for our lower-end machines when I worked as a PC technician at a retail shop.
The warning on that SCSI port is so that you do not connect a printer to it making the computer unbootable (has I myself did once...)
I just encountered an SBLINK interface on an ASUS P2B-DS motherboard I dug out of my basement, apparently what you mention around 16m20s.
Yes! That's the name for it. I think the other board that I have with that connector might be the same Asus model.
On that last mobo, it can run 386DX compatible CPU's and utilise the space inside the 486 socket to host a 387 FPU. I have a similar board that implements that setup and it's quite a neat idea. The fact it has VESA slots on it as well makes it quite rare, as it's uncommon to have a 386 compatible board that can host VESA cards.
Also that other chip is EFAR not Fear.
You are surprisingly rough on your stuff considering how rare some of those are today
Yeah... I was... getting a bit frustrated with that last screw and standoff. I was trying to not let it show in the video, but I guess I didn't hide it all.
Damn, I'm jealous of quite a few things! Well, not jealous so much as want in my collection lol still no Pentium Pro.. Nor slot Xeons actually but there's one beast i have that you'd love. A Compaq ProLiant 4500 with Quad Penium 100MHz CPUs and 256MB EDO RAM i salvaged some years back, got it quite cheap as it wasn't working and fixed it up. She still boots fine, all SCSI drives (4x2.1GB) and sadly the original SCSI CD-ROM died on me installing Windows so i replaced it with a SCSI DVD drive from an old SUN system.. Which was welcome as that was 40x CD, the old one was 2x.. I could install Win 2000 Adv Server in 20 minutes instead of almost 2 hours!
I had the first case in the early 2ks but it was ATX
EISA + VLB, JACKPOT!!!!!!
No kidding! I was pretty excited to see that.
I personally love the Compaq torx screws over standard Philips head screws. They are much less likely to strip and are always the same size amongst all Compaq and several HP models. On top of that, you can use a flat head if you don’t have a torx bit handy. I wish more OEM manufacturers used it. Now security bits are a different story. Absolute trash.
i feel your pain my friend ive been buying at least 1 pc tower a month 4 nearly 2 years now and ive filled my box room so i 2 have a problem lol
rhat e-isa bus one is probably a database(my bet) or file server.
tape drive? yeah server.
scai, server
probably a raid card too for the scai controller
I would have disconnected the Hard drives to start with, sometimes bad hard drives can prevent the computer from starting.
Hi there, you shouldn't expect any socket 7 Intel chipset with AGP, they sent Socket 7 to obsolescence and the low power mobile market as soon as they had their first AGP chipset for the Pentium II with the LX/EX chipset (66MHz FSB) before rhat Pentium II 233/266/300 with 66MHz FSB came without AGP using chipset inherited from the Pentium Pro (440FX).
Edit... BTW I see no problem there! 😅
Be nice if that first system is a Socket or Super Socket 7 board..
I WANT THAT AOPEN PLEASEE!!!!!!!!!!!!!!!!!!!!!!!!!!!
i have a similar problem with sound cards
Oooh, WEITEK GPU, that is a RARER Accelerator, it is in fact 3D accelerator for CAD!!!
That card is in fact 2 cards, one 2D thje other 3D
Do you know what sort of 3D does it has? I thought those Weitek chips were just Windows GUI accelerators. I guess fast, high quality line drawing is all you'd really need to CAD in those days.
@@TalesofWeirdStuff Check auto-cad from the same year or one or two later.
Final one's the same case as my first Pentium 120mhz Different mobo though.
I scored a working PCjr at the curb for free. Someone was throwing it out.
Oh look the same PROMISE VLB cached controller I used back in the day on a DX50 NOVELL NETWARE 3.12 Server....
And yes DX 50 not DX2, first CPU to need an heatsink.
Hope your Expo went well! Important: Don't buy more than ya sell... (-:
That board supports both the 486 and 387 on the same socket. I have a similar board (only VLB though) lucky basterd.
Careful they are not oriented the same way!!!
Poor HDDs. Continous spinups and spindowns for minutes. What a torture they got in 1st machine's "test".
