Hi All,

I came across this board and was wondering if anyone could shed some light onto what it was and what it maybe came from?

16KB memory board for something
(the National Semi MM5280s are 4Kbit DRAMs)

Wow! Great responses - thanks!!!


The document that mentions the RAM Board specifies that the 14502301-001 model is an 8K memory unit, so it would certainly be reasonable to assume that the '14502301-001-B" board is indeed a 16K memory unit.
