hi guys
I found an old PII slot A with a motherboard marked 94V-0 and a logo that looks like PSC

Hi,
I've met "94V-0" on different boards of different manufacturers. It's not special.
I would try to find a manual on theretroweb site.
Good luck!

Hmm it has no manufacturer name or model number on it. Only Made in Taiwan Rev 2.1

Layout looks very similar to this: https://theretroweb.com/motherboards/s/dataexpert-mlx8440

Differences I can see are that the floppy header is nearer the edge of the board, it doesn't show the header in the corner by the RAM, and has an AT keyboard connector rather than PS/2. But the USB and IR headers are in the same place, and the multiplier and bus speed jumpers look to be labeled the same. Can't find anything more about the board though. If it boots then maybe the BIOS string can be used to help ID it.

If you were able to run it, you could identify the manufacturer by its ID from the bios string (which appears on POST).

Its very special, as Babasha said it means PCB material is fireproof 😀 https://en.wikipedia.org/wiki/UL_94

Yes it is running, but one of the hard drives Seagate 6.4Gb does not spin and I think this has the OS. The other one Quantum 3Gb spins and detects but I can't boot from it - possibly it was the data. I tried a 20Gb HDD which I am pretty sure hsad Win98 on it already and it detects but it says the HDD does not contain an OS

It actually came as a complete PC with Matrox Mystique that has an add on RAM card (I think it is), Creative Voodoo 2, Awe 64 ISA and an ISA modem card. Everything seems to be working, I'll try installing Windows 98SE on another small IDE drive and see if it boots. It would be fun too, if i could get the 6Gb to spin up I may be able to close the OS from it before it dies again

I'll post back once I get win98 running

take a picture of the POST screen with BIOS string visible

I put a video of this motherboard on Youtube

You can see the BIOS ID here

According to google this is a Fungus Motherboard? 440LX/EX chipset

I now have all the drivers installed plus the Mystique, Voodoo 2 and AWE 64

Just some USB device driver comes up as not installed

I don't know and can't find anything about Fungus (makes for interesting search results), but interesting that the only Fungus board listed on RetroWeb is a rebadged DataExpert, which is the same make as the link I posted earlier for the board that looks very similar to yours. There's a short sheet for that board which includes DRAM options and jumper settings for CPU speed. Would be interesting to know if that matches the silkscreen table between the CPU and RAM on your board.

@39:58 as I said manufacturer sticker on the ISA slot
Sometimes it pays to click on the second link in google results http://wims.rainbow-software.org/index.php?start=60&count=30

gj snufkin 😀. Picture should probably go (with permission) on theretroweb on that entry, as its just different revision of same model.
