Sorry, no p500 here. I'm not eve sure how I acquired this B, to be honest. I could indeed change the code to handle the condition via dummy bank reads, but the PCB has to be modified anyway. At present, the CPLD sticks out beyond the 6509 footprint on the bottom (by pin 20/21), but it interferes with the B keyboard cable. So, it has to be moved to be at the top (pin 1/40) anyway. Right now, I sidestepped the problem with a riser on the socket, but then the B PSU interferes when attempting to close the case. (Sure, should have noticed this when designing the board, but who pays attention to those details when one is just fiddling with an idea like this late at night? I suppose all of you do, but I did not). Jim Message was sent through the cbm-hackers mailing listReceived on 2018-03-02 16:00:03
