Thanks for the link, that was a very interesting read.
However, isn't there a mistake in the Motorola
68000 description. Doesn't
i=
t use 32-bit addressing and not 24-bit?
The addres _registers_ were 32 bits wide, but only 24
address lines were
brought off-chip. There are actually 23 address pins
(A1...A23), becuase
A0 is determined from the states of UDS/ and LDS/
