Summary: Mac II and the 68020 instruction cache, can it be turned off?


The November issue of Macworld talks about Mac II compatibility with various
software packages and lightly goes over some of the reasons for incompatibilities.
One of the reasons is the 68020 and its instruction cache.  If the program
self modifies code then a crash is in the making.  Seem to me I read some where
that the new Atari and the Amiga have ways of turning the instruction cache off.
Would the same be applicable to the Mac II?

I also would like to start a dialog going among other Mac II owners about
which applications, games and programs work on the II.  I have a high horse
power machine sitting on my desk with no software that takes advantage of the 
68020 or the color capabilities.

Thanks in advance,
