Would this be an I/O card but what's with the memory? I/O + RAM expansion? Or cache for HDD? If that was a thing for 286(?) or 386(?)
Looks like a RAM expansion board with two serial ports.
I can't decipher the markings on the big chips near the bracket, a better picture of these could probably help.
Proud owner of a Shuttle HOT-555A 430VX motherboard and two wonderful retro laptops, namely a Compaq Armada 1700 [nonfunctional] and a HP Omnibook XE3-GC [fully working :p]
the chips are 82c450's, which are serial port chips (56k).
and two 40 pin ide connectors maybe but I dont see any chips to control them.

Looks like it says 386 SIMM RAM W/2SP, so RAM expansion with 2 serial ports and what looks like two IDE ports

Constantly being worked on. Feel free to message me with any corrections or details of cards you would like me to research and add.
yes looks like 386 SIMM RAM silk screened. Looks like a Wang (or similar) keyboard connector top right of the card, only 5 connections to the Hi bits on the ISA connector so it can not be true 16bit memory interface to the board unless those 40pin connectors go to a proprietary mother/daughter board....not enough parts for IDE controller from 1990.
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
Thanks. I think I'll leave it then. Would have to find the missing 95% I guess.
