It's been said that the 6800 inherited a lot of ideas from the PDP-8, and I agree with that to some extent. The ISA is actually very clean and neat, once you wrap your head around it - I used to program 6800 assembler professionally, my first paid job as a programmer! Unlike the PDP-8, I/O is memory-mapped. Depending on what monitor ROM you have (if any), you may have different system services available. One very useful system is the one that can read S-records from the serial input, allowing you to easily transfer programs onto the machine. If you want to grok the 6800 in fullness, there are online scans of Motorola's programming manual for the device. Another great resource is the swtpc.com site, even if you don't have a SWTPC machine (what do you have?). Have fun with it! Cheers -- Ian -- Ian S.
