Adapter Cards

The PS/2 models had between three and eight expansion slots for MCA cards. The standard desktops had three, the towers eight, and the large desktops five. This is just a list of the cards I, personally, own, or rather, owned in 2005. The lot that I bought in December of that year added a few more, but I never got around to update the page.

IBM Cards

8514/A Graphic Card (3)

16 bit.

4-16MB Memory Expansion

32 bit.

SCSI Card (3)

16/32 bit. External connector is "mini-centronics", cables cost a fortune. Internal connector is non-standard on the card, but standard on the devices.

ESDI Hard Disk Attachment (2)

16 bit.

3114 Scanner Adapter

16 bit.

Token Ring 16/4 Adapter (11 I think)

16 bit short. I'm not particularily keen for them, but about every other PS/2 has one installed.

4216 Postscript Pageprinter Adapter

16 bit "sandwich". 25pin male connector.

WaveRunner Digital Modem (2)

16/32 bit. They were in one of the 76is and one of the 85s. I found a product evaluation on the web.

FRU P/N 81F8823 Memory Riser Card for Model 90s.

Third Party Cards

3Com Etherlink III

16/32 bit middle length. I currently have it installed in the 50, it was originally in the 56.

HP ScanJet Scanner Adapter

16 bit.

National Instruments MC-GBIP

16 bit. This is an adapter to control machines through the computer, if I understood it correctly. I even have a matching cable. I just don't have a machine to control.
