   ZENITH 386/20

      CPU:  80386-20MHz
      SIMM Sockets:  8
      Standard Memory:  4MB (4 1MB SIMMS)
      Maximum System Board Memory:  20MB
      Intel Matched Memory Compatibility:     PCSM 1170 (1MB)
                                              PCSM 1455 (4MB)
                                              PCSM 14Z3 (4MB)

      The PCSM 1455 and PCSM 14Z3 can be used interchangeably in this
      specific system.

      The SIMM sockets are numbered from 1-8 starting at the left side of
      the system board board.  Because the Zenith manual may be incorrect,
      see "Correction to Zenith Manual".

   CORRECTIONS TO ZENITH MANUAL

      While testing certain Zenith 386 computers, Intel uncovered errors in
      the manuals.  Zenith has verified that the following information is
      correct:

      You must install 1MB SIMMs in slots 1-4.  After filling those  four
      slots, you may install either 4MB SIMMs, 1MB SIMMs, or certain
      combinations of the two.  You don't have to fill all the slots, but
      you must fill slot 5 first.  Fill as many of the remaining slots as
      desired in ascending numerical order (or leave them blank).  If you
      combine 4MB and 1MB SIMMs, insert all the 4MB SIMMs first (starting
      in slot 5) then insert as many 1MB SIMMs as you desire in the
      remaining slots.
