<>Memory

This mainboard supports 4 x 30pol. and 2 x 72pol. SIMM Sockets for a total size of 128MB Fast-Page-Modules. Basically, there are 3 ways of memory configuration:

  1. 30-Pin-Modules, only: 4 same modules.
    Modules in sizes of 256 kB, 1 MB, 4 and 16 MB are supported.
  2. 72-Pin-Modules, only (1 or 2 pieces)
    Modules in sizes of 1, 4, 16 and 64 MB are supported.

  3. Mixed (30Pin and 72Pin)
    insert same modules in each of the four 30pin-sockets
    then the 72pin-PS/2-socket next to the 30pin sockets must be empty
    then the second 72pin-PS/2-socket supports modules with at least the same size as all the 30-Pin-modules together. For example: if there are 4 x 30pin modules with 1MB each, the PS/2-module must have 4 MB or more.
