                Size                                 Cache

                512KB                             (2) 256K x 9

                 2MB                               (2) 1M x 9

                 8MB                               (2) 4M x 9

       Note:When configuring the cache, both SIMM sockets must be
       occupied with identical SIMM's; i.e.: two 256KB, 1MB, or 4MB
       SIMM's. The modules may be 8 or 9-bits wide and must be 80nsec or
       faster.

                       MISCELLANEOUS TECHNICAL NOTES

   Warning: Do not reset or power-down the system while the drive active
                LED is lit! Data in cache RAM will be lost!
