      The following information pertains to the:

            Compaq SystemPro/LT 386/33-210, -510, -680
            Compaq SystemPro/LT 486SX/25-210, -510, -680

                NOTE: International models of these systems come standard
               with 8MB; for memory upgrade information for International
               models please see the Compaq SystemPro/LT 486/33-210
               section.

      These Compaq Deskpro systems come standard with 4MB on the system
      board. These system boards are expandable to 64MB using Intel 72-pin
      memory modules in a Compaq 60MB memory expansion board.

      NOTE: Adding memory beyond the processor board's 4MB of memory
               requires purchasing the optional Compaq memory expansion
               card (Compaq part number 129160-001).
