Clem Cole scripsit:
the 68000 and 68010 were 16 bit internals. ie a 16 bit
barrel shifter
and it took 2 ticks to perform 32 bit ops. a natural int was indeed
16 bits in the base registers although they also could be used as
32 bit registers (2 ticks ) so some 68k compilers defined int as 16
others as 32 (more in a minute). it technically was LP32 not ILP32
Sounds like the 8088, which used an 8-bit bus but 16-bit registers
and operations.

Sir, I quite agree with you, but what are we two against so many?
