Actually the 68010 is an slightly improved version of the 68000. It has support for virtual memory (using a separate MMU chip), some extra instructions (move from CCR & SR, move to/from control register, move from/to address space, return an deallocate parameters), a different stack format. And it has a special 'loop-mode' which means that there is a little prefetch queue so that DBcc loop with one instruction can run from the queue thus reducing instruction fetches. Thus a 68010 will speed up programs with many one instruction loops.
>>OK, thanks for the info. In that case, you probably could replace the chip and write extra software to take advantage of it. Maybe you could do something along the lines of the BJL mod switch (look around...) - it uses a SPDT switch to control which of the chips power supplies is connected to the board (it is designed for using a developer BIOS, bu the principle is the same).
But badly written programs that rely on the stack format might fail.
>>Yes, the Jag has plenty of them ;)
Well thanks. If anyone wants to mess up their Jag, please do so in the interests of science ;)
