I had a look around and worked out how to read the user port in BASIC,
when I do it would seem that it reads all the pins as high, I gather
this is the default condition. Does anyone have a pinout diagram for the
user port connector on the bottom of a BBC B? And in order to change
states, do I just ground a pin?


Thanks,


Tom
