Some 72-pin RAM SIMMs arrived today, bought and shipped two days ago. Postal service tends to be a day late because of the increased demand, but that's alright.

€15 for the lot, which is more than fair, I think. Untested, and the seller couldn't ID all of it, so my sleuthing comes down to this:
- Top left OKI MSC23232C-70DS16 double-sided pair is 8MB each, 16MB total. Not 100% sure if it's FPM or EDO.
- Bottom left LG Semicon GMM7322110CMS single-sided pair is 8MB each, 16MB total, EDO.
- Bottom middle Motorola MCM32T216SH70 single-sided pair is 8MB each, 16MB total, FPM.
- The four remaining sticks are Hyundai GM71C17403CJ6 double-sided, 32MB each, 128MB in total, EDO.

My hope is that I can succesfully revive my LS-486E board, and use the 32MB sticks to max it out at 128MB (according to online sources). The only confusing part is whether the board will support EDO or not. Online results are conflicting for the C revisions, some claim it does, some claim it does not. The manual I found for what seems to be this revision claims it does. The board came out of a beat up Photoplay 2000 cabinet, and currently doesn't work, but the RAM it was fitted with seemingly from the Photoplay factory was EDO too, so maybe it'll work? Maybe it's to do with memory density? We'll see, I'll first need to revive that board before I can test that. Either way, it's good to have this RAM on hand, I'm rather low on 30-pin and 72-pin SIMMs anyways.

Picked up a Nice ATX Socket 7 TX motherboard. Gigabyte 686ATX4 - I believe this is a very late socket 7 board. Does anyone know if there is a modded BIOS for K6-2 support, not seeing much info on this board.

Try here for K6-2/400 support on your board

https://www.gigabyte.com/uk/Motherboard/GA-58 … support-dl-bios

nice board 😀
the gigabyte site says "Support up to AMD K6-2/400"

I was supposed to get a GA-586ATX a while ago that I scooped up on ebay for really really cheap... but the seller never shipped it and never replied back either 🙁 no paypal unfortunately.

got another PICMG board though, including a Pentium III 1.2Ghz
spotted only one bulging cap

Hey, this looks almost identical to the one I got recently..?

Next scrap pile 😁 Made the seller an offer which he declined. At the end I got it cheaper than that....

Really difficult to spot the usable parts in it....most important task will be to get rid of all the remaining junk again when I get it 😉

yours was also an iEi iirc, but quite a different model... I saw that pile and dismissed it because of all the extra junk x3

Some interesting stuff in there! There appears to be what's left of a Commodore brand IBM Compatible in there, consisting of its two interconnecting boards. If anything it'd be worth selling on for parts if it's still in OK shape, or maybe sticking in some case to make it a PC again. Also some neat ISA, PCI and AGP cards, among what appears to be VCR and other A/V PCBs.

Correct. Its the Commodore PC10 (XT). Board is divided in 2 parts

Also asked for the case but seller didnt know what I am talking about...

I love lots like that. So much fun to dig through.

I spot an MFM + Floppy card on the left and a Cirrus Logic GD510\520 ISA card in there. From what I've read they are known for excellent (near perfect) CGA compatibility, where as many other VGA cards have issues. Would probably make a nice card for a 286 or 386. I'm sure it isn't very fast, but for a system that may dabble in really old CGA games it may be handy. 😀 I have at least one of these (and another one that's similar) but have yet to really tinker with it. I know they're fairly uncommon though.

Certainly a good sign for that pile. Who knows, maybe the whole bottom layer is all ISA sound cards. 😱

EDIT: Almost forgot... my absolute favorite thing about these really old parts is that they almost always work. They are very light weight and have very few fragile components on them, so they can take a beating. Compare this to scrap lots with late AGP cards. Ughh... I think only about a third of the cards I find made after the year 2000 have all of their SMD components intact. Once you hit the FX and Geforce 6 or 7 series I'd say about 10 percent have survived unless they're in boxes or antistatic bags. I have very little concern with static but those bags have saved SO many cards from having all their SMD caps sheared off.

PODP3V125 - latest addition to my growing family of Pentium Overdrive chips:

Today there was a good buy-at-once offer for a Commodore PC10 case with PSU. I was sure I got the corresponding board longer time ago in a scrap lot and repaired it. Therefore this would be a perfect match.
Just found the board and happy to get the system complete without having space for it 😁

heh nice, that has been there for months iirc ^^... I contemplated about getting one of those for a while just because I like the look but I wouldn't have any commodore stuff to put in, so I'm glad to see that happen ^^

I saved a boatload of hardware from scrappers today by going way above my comfortzone in bidding... like literally all of the bidders apart from maybe one or two with lower bids were scrappers... there were about five 486 boards with VRMs and one with some other local bus... theoretically just worth it for those if they work, only one of them seems to be corroded.

was three seperate auctions, one with a bunch of simms and coast modules, one with like 20 boards and one with a bunch of gpus a SB 2.0 and some other cards.

.snipped out some of the seller's pictures:

this seems to be an Opti Local Bus board? good luck to me ever finding a fitting card x3

I'm sure someone of you can tell me where this one belongs to ^^

some of the other boards... the hyundai board seems to have quite bad corrosion, the others look pretty OK
on one the battery leaks quite badly but the board looks fine

The one on the bottom left, which one is that? When I zoom in, I cannot see the markings. I never knew Hyundai made motherboards or computers.

looks like this one: https://www.vogonsdrivers.com/getfile.php?fil … 471&menustate=0

I haven't found much about the hyundai board yet either, I did know they made computers though.

Are there any other markings on the Hyundai board? Good haul as well.

Got a bunch of 486 parts today. Moscow is in lockdown now, so I've used a delivery service — which resulted in seller packing quite a lot more stuff than I asked for...

Iwill SIDE controller: SCSI, IDE, floppy, LPT and COM on one port. Someone took the BIOS chip — if anyone has a BIOS image, please let me know.

A regular VLB controller.

An unknown SIS471 VLB board without jumper description:

Gave me some beeps with the wrong RAM. Once I changed the RAM, it stopped giving any kind of feedback. Then I tried a few other DX2s I have. Intel ones didn't work, but I had some progress with Cyrix DX2-66. Some text appears on the screen, but after a second everything disappears. In other cases there would just be a green rectangle in the center row of the screen.

Another SIS471 — no BIOS chip.

A UMC-based motherboard, supports only 5v chips. It works, so I immediately replaced the barrel battery.

A-Trend OPTi-895 Deep Green Model 1442G. It worked with an Intel DX4, though it occasionally gives the "no keyboard error" (even though the keyboard works even then). It also reports 0KB L2 cache even though the motherboard obviously has 256 KB. Any way to get rid of the "no keyboard error"?

PC Partners PCI board with a UMC chip. Works.

Another PCI board with an ALI chipset. Works.

A PCI-400 motherboard. Doesn't work.

A DataExpert EXP4045 motherboard — doesn't work.

A 486SLC board with a VLB and an FPU. Doesn't work.

Some controllers and VGA cards for ISA.

nice 😁 more 486 boards
also that 486SLC board is an Alaris Leopard including the FPU 😀

I'll be able to tell when I get them ^^ only other thing I can decipher is "DX4 CPU 100" and what looks like "GA-486V3S REV/D" ...gigabyte OEM it seems.

Nice. I wish I found this as I have a matching card and keep looking for a board 😀
