Hello Vogons!
I've finally made an account here in search of help. I've had this old board in storage for a long time, it was my dad's computer that he got probably around 1990-1992 and I've been wanting to put it in a case and get it running again.
I've been searching high and low but I can't seem to find anything on this motherboard, it uses the ACT A27C011 chipset, and has two AMI BIOS chips. The sticker on the daughterboard ISA slot alludes to it being a PC-Chips motherboard but nothing I've found matches mine.
I've put images into an album here, pardon the dust on it https://imgur.com/a/E8eHdbe

Thanks!

Looks like PCPartner numbering scheme. Do you have the card for that long ISA-like slot at the bottom? I don't see a provision for RAM otherwise.

Hate posting a reply and then have to edit it because it made no sense 😁 First computer was an IBM 3270 workstation with CGA monitor. Stuff: https://archive.org/details/@horun

Yeah I added it to the album, looks like I made it in time before Horun linked the pictures in the thread. And I think I agree that it's a PCPartner board, looks similar to the PCPartner 486SX M.

Guess there's nothing to do but to try it out and see. Are those 256KB or 1MB SIMMs on the RAM card? And it's odd that one SIMM is off to itself instead of all twelve of those sockets to the right being filled.

I am actually unsure, I forgot how much my dad said was originally in there but knowing him it was probably 1MB SIMMs, that lonely SIMM is there because at one point they were all populated, some SIMMs came off over time unfortunately. So I'll probably want to fill in the slots. I also have no way of testing the board out unfortunately as I don't own an AT power supply right now, or have any way to get video off of it for that matter.

It will work with 12 SIMMs, just move the single stick to the vacant 12th slot on the right.
And there are cheap ATX-> AT power adapters available.

This board might also need recapped before I think about turning the power on. Trying to Identify all the caps is gonna be a project for tonight.
