       A  An alternate would be to put PCSM 1290s into sockets 3 and 4 in
          addition to the 4MB memory modules in sockets 1 and 2.

   IBM PS/2 MODEL 80

      An Above Board MC (PSMB 5300) can provide true 32-bit memory from an
      expansion slot for these IBM PS/2 Model 80s.

      There currently are NOT any Intel Matched Memory module products that
      can upgrade motherboard memory in these IBM PS/2 Model 80 because of
      the design of these PS/2 Model 80 system boards. There aren't any
      SIMM-type sockets on these motherboards. IBM relies on its
      proprietary memory boards or a third party memory board in an
      expansion slot (such as an Above Board MC) to add more memory to
      these systems.

   IBM PS/2 MODEL 90-0J5, 0J9, 0KD

      These PS/2 Model 90 computers come standard with two 2MB memory
      modules on the system board. These system boards and are expandable
      to 32MB.
