Had to take a break from the Stunt Cycle as I was going in circles.
Started with this board and I have a clock signal and it gets broke down as expected. Board is watchdogging, signals look low on all pins on processor. Hook up FlukeEmu and it says I have a DB 1 pin held low. Poking around I am thinking of pulling ROM chips to test but I can't find anything about these chips on line. When I do a google search it comes back with something definitely not these chips.
I have another board #2 which had a bunch of broken chips. When I pulled the ROMs they broke in half. They were also labeled cryptically. The board with ROMs pulled does not have DB1 being pulled low, it comes back as Buss OK but there are no ROMs and the other chips might be necessary but these other ROMs on board #1 are soldered down. If I can test them then I will pull them, I probably have to pull them either way unless I can make new ones to test board number 2. Board #1 looks the same weather the processor is in the board or not. No code from ROMs.
