The original Mac(128k), "Fat" Mac(512k), plus, and SE(?) all used 68000s.

Anyway, If you call Motorola and ask nicely they'll send you any manuals you
ask for on any of their stuff for free.  They probably also have it on their
website by now.  The one you're probably looking for is "M68000 User's
Manual", Motorola part #M68000UM/AD.  You'll also need to know about the
functions in the 89 ROM to do anything useful...info on that can be found at
TI's calc page.

HTH,
