Today my son got the Stage 1 board to work. He made some initializing code for the board and the serial controller and translated WozMon to 6809 in assembler. He wrote it to an EEPROM and we got echo from the code. We did not get the actual monitor to work entirely, but still, an echo means that the code still initializes the board and the serial controller correct, and the key read routine in WozMon works!!!
Oh Happy Day!
So more debugging and faultracing tomorrow…
