System Memory

Both Type A-1 and Type A-2 system boards support 72-Pin, 60 or 70 NS, tin-lead, fast page or EDO, 32 or 36 bit Single Inline Memory Module, (SIMM).

Type A-2 can also accept a 168-Pin 60 NS, Gold, or EDO, 64 bit Dual Inline Memory Module, (DIMM). See SIMM Configurations below.

SIMM Configurations Board Type A-2

Factory-installed SIMMS are non-parity SIMMS. However, both parity and non-parity industry standard SIMMS are supported.
When installing SIMMs, run the Setup Utility to clear XX62 or 164 error codes.
