thanks!
So if your hardware can't tolerate a read access to
a register, then you
can do a MOV #0,ADR instead of CLR ADR (and make a note in your code why
so some poor soul 30 years from now understands why you are doing a
non-optimal MOV #0,xxx!)
I fixed the hardware :-) I was just curious about which machines did
what.
The problem was that the two transactions are back to back and the bus
master keeps overnership. I was waiting for BBSY to go away...
