From this lot, I was able to identify a TSENG ET3000AX Combo EGA/VGA card, a Voodoo 1 4MB by biostar, an Aopen VI15G 486 VLB mainboard witch I got running with a 50MHz Intel 486DX, a Goldstar / Promise VLB IDE controller and a Matrox Millenium. Included were also some Creative sound cards witch were easy so I won't post pictures of those, and some other sound cards I'll photograph and post later.

The AOPEN / ACER VI15G 486 VLB mainboard set up with a 50MHz intel 486DX + Goldstar / Promise VLB multi I/O + Cirrus Logic VLB video + Seagate 1.6GB. It was a little hard to get the system stable at 50MHz due to the weird jumper setting for VLB bus configuration. Benched at 33MHz just fine. Not the fastest thing in the world...

The Voodoo 1 + Matrox Millenium:

Unfortunately the Matrox doesn't work. It's my second defective millennium card. I seem to have no luck with these... 🙁 The Voodoo works perfectly. My first VOODOO1 YAY!!! Planning to play uprising later 😁 (It won't work on any of my other 3DFX hardware, but started up fine on the V1 😁 )

Detailed pictures of the big ISA card - seems to be some sort of System on a Board since I spotted a 10MHz Intel 80286, but it's obviously incomplete...

I managed to identify one of the older motherboards - the one in the 1st post, last picture, bottom left. It's a AUVA COMPUTER INC CAM33-P2. It only supports 486DX and DX2 processors. Link can be found here: http://motherboards.mbarron.net/models/486isa/cam33p2.html

Also identified the combo 486/386 board in the 3rd picture (first post) - bottom right. It's an OPTi 495SLC board by an unidentified manufacturer. Some boards came with soldered 386 or 486SX processors. My board is a late version and does not have the 386 132 pin socket soldered on, but mounting one won't be too difficult. The problem is it's EEPROM came with the sticker removed and BIOS information is corrupted. I'll need to find a copy of the bios. A link with board layout and jumper settings can be found here: http://museum.ttrk.ee/th99/m/U-Z/31693.htm

Also, it seems that the "bigger" 30 pin simm modules are 4MB in size. Found out today while testing out one of the tiny 386 boards with soldered AMD 33MHz SX together with a 25MHz Intel 387 FPU.

I have the older version of your hybrid 386 / 486 board. I'm still in the process of learning how to dump and back up all bios chips I own of the hardware i'm looking preserve.

One it's dumped it shouldn't be a problem sending you a copy, as you already own the board and bios, non-functional allbeit.

The green card with an wide external connector in your first picture could be a external floppy controller. I have seen a similar one, but the number of chips on it maybe indicate something else.

Any chance you can redo the pics for the items you haven't identified? Would make it easier on us to help out =)

This is 5 years old...

I'd be happy if someone would solve my "unidentified" threads even after 5 years 😁
