As far as I've been able to determine the ST does no checking on boot for
the type of 68000 installed. Therefore the exception handling routines in
TOS will bomb (ie. lockup) miserably. Further (and I've mentioned this
before) some dimwit went and put the exception numbers in the upper byte of
the exception vectors!!!! Odviously this will give you an 'E' ticket into
the Twilight Zone on the 020!
Much of the system software in the ST is really JUNK. In Atari's defense
however, they never claimed upwards compatibility among future machine
archetectures (SP?). Still I'd pay another $50-$75 to get a new version of
TOS in ROM (2.0 ?). No, this is not rumored. I just want Atari to know if
they ever WERE to decided to re-write some of TOS/GEMDOS themselves (and
get it right) instead of DRI's junk, *I'd* be willing to pay for it.
Neil? Others???? Comments???
