Does anyone know of a way to access the HP9836U graphics memory using
assembly? According to the manual, the memory resides from $530000 - $53xxxx.
The problem that I had was that the O/S wouldnt let anything reference outside
a predetermined address boundary.

I tried to set the 68000 supervisor mode on but that didnt seem to be working

Thanx mucho
