> I am massively hampered in this task as I don't have any experience of assembly programming 6800 or similar CPUs (or indeed any micro processors). Are there any good resources online I can download, or books I can buy to that will get me on the road.
Long version where I answered that question on my blog:
Short version, get this; "Understanding Small Microcontrollers" by
James M. Sibigtroth:
6805 is close enough to the 6800 that you'll get the concepts.
I used the EPROM version of the 6303 long ago. It was touchy to the
reset pin timing.
If it only has a pull-up and cap on the reset line, make sure that cap
hasn't go bad.
Do you truly have the ROM 6303 or do you have a EPROM 6303 (6703?
Doesn't look right.)?
Think I do still have a 6303 Op-Code Reference Cheat Sheet here that I
could scan, if that would help you out? I know I got rid of the data
books long ago.
