I've been playing around with exception vectors today and ran into a
problem. Whenever you try to directly change any of the vectors (actually
the only one I've tried is the illegal instruction vector), the calculator
gives a protected memory violation error. Now, this error does not lock up
the calc. It's like a typical TI-92 error dialog box. Although the calc
doesn't lock up, fargo is disconnected and unreachable at this point.
I've tried a few things, including disabling interrupts by putting $2700 in
the SR before writing to the vectors, but nothing seems to work. I always
get that error.
Any suggestions?
I'm rather new to programming on the 92, so I may be missing something, too.
