IBM PS/2 16-bit Computer 15F8289 MCA 2-8MB Memory Expansion Card.
16-bit MCA architecture (PS/2 model 50, for example)
4 72-pin simm slots (no RAM installed).
My PS/2 machine died before I had a chance to try this card, so it is UNTESTED but originally described as working when I bought it. No warranties are implied and no returns can be accepted. Sold as-is.
Shipped with USPS First Class Package.
