I have found (by talking to Broderbund) that on the newer machines
with the instruction cache, their protection fails (DEATH TO COPY
PROTECTION!!!!).  Anyways, there is some cdev called something like
"toggle cache" or "Cache toggle" or whatever that turns of the
instruction cache and lets some of these programs work.  This worked
for me with Playmaker Football and Simcity (non-color).\
