Last night, I finally made it into the basement to dig
out something
like this. Found a M8044-DC (obviously a MSV11-DD) and a M8044-DF
(apparently also a MSV11-DD). Both have regular 16k*1 chips in a 4*8
array. I didn't find a difference between M8044-DF and -DC (rev level,
perhaps?), aside from one using ceramic Hitachi chips (HM4716A-3) while
the other has plastic Fairchild ones (MB8116E).
You found the difference... the 'x' part of M8044-Dx is the vendor
who supplied the chips which went on the board.
