I have the pinout here in my M68000 Family Reference Manual. I could
find some way to replicate it in ASCII sometime between now and "the distant
future". :)
I have a Hitachi 68450-10 and a Motorola 68451-10 -- both PGA -- that I
dug out of a bin of chips at the local computer bastardization and surplus
hell-hole. Someday they'll go into my fabled homebrew Linux/68K machine.
Heh. Right. Does anybody happen to know what the 68451 actually is? I've
been assuming it is some slight variation on the 68450, but I don't have any
documentation that actually says so outright.
