1 P70 CHARACTERISTICS Microprocessor Intel Clock 2 MHz Architecture MICROCHANNEL Memory System board can support MB installed on 2 banks: Two configurations are possible: 2 MB on system board ( SIMM 2 Kb x 9). Expandable only by replacing these SIMMs with those of Mb x 9 EXM 207 MB on system board ( SIMM Mb x 9). Expandable by installing more SIMMs Mb x 9 EXM 207 System memory can be furtherly expanded via a MB memory expansion board MEM 20. This board can be expanded to MB via SIMM Mb x 9 EXM 207.
