I don't find that surprising. At the time they were designing the
KA730, 1M boards were obviously available (or imminently available)
and with 5 memory slots vs 8 in the KA750, I'm sure they never
expected anyone to want to use up a slot with a tiny board, so why
As part of this thread, I was digging around for context and ran
across ads in ComputerWorld and such as archived on Google Books. The
ads indicate a reseller price of $4,000 for one MS750CA (1MB board) in
1984. By the time I was buying them (for work) around 1989 I think,
ISTR prices around $400-$600

No good reason to.
