Looking for an MC68451 datasheet (or scan). Most of
the ones that turn
up from the usual database sites are actually for the MC68450 DMA
controller, which is entirely unrelated. The only one I found that is
actually for the MC68451 was "Advance Information" from a databook,
and did not include the pin grid (R or RC suffix) pinout. There was a
"loose" (not in databook) datasheet that is more recent, labeled
"Preliminary" rather than "Advance Information", and later versions
of
that include the pin grid pinout. Does anyone have that?
The DIP version datasheet is also in the 1981 "Motorola Microprocessors
Data Manual", page 4-818 to 4-835, but no PGA pinout, sorry.
