I haven't received it yet but I purchased an IBM 5x86c CPU that was being sold as scrap for gold recovery. I got it for $12 shipped!

It's going to take some time to straighten all these pins with a mechanical pencil, hopefully the thing will still work! Fortunately in my experience 486 pins have always been pretty forgiving when it comes to straightening.

4x8MB EDO RAM

The two modules at the top are interesting. How can 3 (or 6 if double-sided) chips result in 8 MByte?

Bough this "new old stock" AT case for €40 incl shipping. It's more of a Pentium case than 486 case, and has no MHz display, but still... It's so clean and shiny!

This is a mystery that has thus far gone unresolved in my build help thread.. The only explanation I can come up with is that these are 2MB 6-bit modules and it's an 8MB 36-bit parity ram stick with 4MB Parity.. If that even makes any sense.. There's no way to divide 32-bits into 6 modules anyway so it has to be 36-bit..

If anyone has a better explanation I'm all ears 😀

Got the same case over here, currently holding a Gigabyte 586ATV with Intel Pentium 75. Mine was missing its rubber feet and thus got a little rusty underneath.

The mainboard can be easily installed by removing the plane together with the AT slots. The plane itself is hold on rails. So by undoing two or three screws it can be easily pulled out from the back.

Got two Deskstars: 7K250 41.1GB HDS722540VLAT20 and 7K80 82.3GB HDS728080PLAT20. 7200RPM, 2MB buffers, IDE. Both models actually use the same areal density (~83GB) and very similar exterior casings, but the 7K250 drops a head for 40GB and is based on an older architecture.

Both checked out fine. The 7K80 will be the main boot HDD for my "Christmas 2005 budget s754" build.

I bought a dead HP ze4500 for 2 € just to take out it's Athlon XP-M, also took a 256 MB DDR SO-DIMM and the 30 GB HDD from it

CPU is an Athlon XP-M 2400+ AXHM2400FQQ4C Barton

Got gifted a free board and 1.3 Tualatin Celeron and 512MB RAM to start my PIII era Windows XP PC 😀

Nice. I really like the colours.

Looks like a P4 board for P3!

That ATX connector? Is it just the photo, or does it look like it's seen better days?

Have had the system in my sig for quite some time now - all 1998 goodness save for the little things like fans, cables and PSU. I saw these STB 12MB BlackMagics on eBay and decided to get them since I regret having sold my 8MB pair for $50 quite some years ago before getting into this hobby. From Moscow, estimated delivery is pegged for April ... 😢

Also picked this up recently, a Diamond Multimedia 4MB MIDI daughterboard. Found it attached to an MX100 Gold sound card in a cheap random bin at the local PC recycle place ( a real treasure trove for this kinda stuff). $3 US 😀

And again attached to my current MX300

Is that a GA-6OXT? If you, I think it's a great board!
It should work with Tualatin 1400 or at least mine does.

And could you perhaps upload some detailed pics of that stock Intel HSF?
Especially of the base and the mounting mechanism and at least a pic of the side without the fan assembly.
I'm curious to see what that Tualatin HSF looks like.

Lets hope for the former.

It is indeed a GA-6OXT with a Tualatin C1.3 on it. AYX is fine 😀 Really happy I blindly got a good board.

HSF photos will be added tomorrow.

Two entirely different AWE32 variations:

Diamond Voodoo

Creative 3D Blaster Voodoo 2 CT6670

And the thing that makes me happiest, the exact type motherboard I need to rebuild the first PC that I owned:

A Toshiba T1950CT that is somewhat of a time capsule. 200MB HDD, 486DX2-40, 8MB RAM - with what seems like its original installation of DOS 6.2 and Windows 3.1 from 1993/1994 on it, whilst it seems to have been parked in 1997. There's even some scientific studies into sexual health in Zambia on there!

It has its flaws though; it needs a proper clean, the belt in the floppy drive has failed I believe (motor whirs but that's all), the power jack is a little flakey (hopefully it'll be happier with its original charger when the seller finds that!) and there's a single stuck pixel in the screen. But the HDD sounds to be in excellent health, and although it had quite a lot of lost clusters, scandisk did not report a single bad cluster. And when I don't knock the power cable, or get it in the right place - it's rock solid stability-wise.

I just picked up an Intel 80287XLT. It's the same as the XL, but in a weird 40-pin PLCC package. I think it mainly saw use in laptops. I'm not sure how many actually used this FPU, it may have only been one or two models.

Good luck trying to fix this.

I even bought a NOS drive trying to fix mine - I've tried everything under the sun and that model drive is just the most unreliable thing you ever saw. Everything has to be calibrated (including the belt length, tension, and pliability) to within a smaller resolution than my precision screwdriver is capable of exacting.

Maybe you'd be better off trying to replace it with some other drive the same size that wasn't designed by an orangutan.

If you have a lot of pins to straighten you can always take a slot blank and straighten them an entire row/axis at a time. Just stick it between the rows of pins and wiggle side to side. I also feel this is safer and minimizes the risk of breaking a pin by exerting too much force in a singular direction. I've saved chips that are in worse condition than that using this method.

Looks horrible! I hope you can rescue it!

My first EISA system, yay ! Except for the battery, everything works perfectly, the original SCSI HDD has no bad sectors. I did not check if the P90 inside had the FDIV bug, but seeing how old is that thing, it might !

Great find... it's like the 386 with a slightly modern look.

Have fun with the EISA bus... great for i/o data transfer speeds. There are also a few graphics cards floating around for it too, i've found and tested a few of them below if your interested: -
