I purchased a Mac II in June and found
that many of my programs failed to run correctly on the
new machine. I originally thought this was due to ROM and
Finder incompatibilities. I am now receiving upgrades which
are reputed to be Mac II compatible and still having
problems so I am more inclined to suspect hardware problems.
Of course, the 90 day warrantly has just expired.
The two programs (besides games) with the most problems are
LightSpeed Pascal version 1.11a and TeXTures 1.0. I have
verified that these programs run correctly on other MacII's.
The bombs aren't totally consistent but usual consist of
BUS ERR8FFC6000 MOVE.L (A0)+,(A1)+
and the nearest ROM trap is
In ROM C826DC0 A05A PrimeTime
OR,
CoPr ERR
or loss of horizontal sync of my monochrome monitor.
Before I try to find an authorized
Apple Dealer, I would like to have an inkling of the
problem. If you have a hardware reference manual, could
you look up the CoPr ERR message or the BUS ERR message
and drop me a note. Any help you might give would be
greatly appreciated.
