[comp.sys.tandy] Switch 68k to 68010

earl@trsvax.UUCP (08/28/87)

   I want to replace my 68000 chip with a 68010 chip in my Tandy 68000 Xenix
   machine.

   Does anyone know what modifications are needed to make the switch work?

   Normally, a changeover from 68000 to 68010 is simply plugging in a new chip.
   But there are a couple of pins that have to be taken care of on the Tandy
   boards.

   Thanks.

Me:  *SIGH*
To Earl:  C'mon, I'm only a phone call away, I'm not in the next galaxy.
To the rest of the net:  I apologise for the public reply, but I thought
that others might be interested in trying the same thing, and wish to
save them the bother and expense of a 68010 chip.

Tandy 68000/XENIX will not run on an '010.  Our kernel does some
interesting things with the stack during bus errors and related
exception processing, the stack format of which changed on the '010.

Besides, if you want to get the performance out of the '010, the kernel
low-level routines need to be recoded to take advantage of LOOP mode.
