Currently there are two configurations - 1 MB on the single FDD units and 2MB
on factory-installed HDD units.

must be one of the following: 2, 4,6, 8, or 10MB (1 MB base) or 4, 6, 8, 10, 12
or 14MB (2MB base).
There are 12 SIMM sockets inside the 386SX PLUS and 256KB and 1 MB 70ns
SIMM’s are used to upgrade memory in 2 MB increments:
