If you are willing to take the bad machine apart, check the mask of the
68000 chip. If it is Moto 0B26, then change it. I've heard that the 8520s
are sensitive to the glitches out of that mask 68000. 'Speed' relys on the
8520s to time operations, so that could also be a problem. My dealer opened
up a new A500 and lo and behold _IT_ had a 0B26 mask 68000 in it. I would
worry that someday, they might have xpansion peripherals that might be
sensitive to the extra noise! PS I ran speed on my A2000 and it crashed. I
located the problem to bad 8520s (I had suspected them bad for some time as
my system clock didn't increment properly {the battery backed clock kept
time, but not the system!})
