I picked up an ISA memory expansion card that I had hoped would work in my IBM 5150 but it is a 16-bit card and requires an AT.
  • Brand: DFI (Diamond Flower Electric Instrument)
  • Model: MEMO-2000A (aka AT RAMBANK)
  • Vintage: Circa 1988
  • 72 DIP sockets for "41256" DRAM chips (120ns or better)
  • Maximum memory: 2MB (can be used with other boards)
  • Comes with nine DRAM chips so you can test it out before deciding to buy more RAM for it
  • Drivers on DOS floppies (160K and 360K) included
  • Drivers are also downloadable from https://archive.org/details/at-rambank-1990/
  • Includes printed manual, but you may not need it as INSTALL.EXE tells you what switches to set
  • Does it work, does it not? I have know way of knowing.
If you're in the Seattle area and can put this card to good use, let me know.

I'm interested. I have an IBM AT that could use it.
