The 386/16 does not use "non-standard SIMMs", it uses regular 256k or 1M
DIP chips on a ZDS memory board that fit into ZDS' proprietary 32 bit
slot.

The 386/16 was ZDS' first entry in the 386 market.  It was based on their
old backplane configuration.  When ZDS introduced the 386/16 SIMM's were
not the standard, DIP memory chips were.  In fact if ZDS had chosen to use
SIMM's people would have called it a non-standard design.  The reason you
have to buy the ZDS board for the 386/16 is that there was no standard for
a 32 bit bus back then.  This machine was introduced before EISA was even
concieved.
