This is something to keep in mind indeed! It would be a pitty to have
homebrews
that will not work on some systems because of different start-up states.

OK I guess I dont have to worry about it then. My concern was mostly for the
B port. Because
that port is more powerfull then the A port and the difficulty switches are
shortened to ground when in the Amateur 'B' position. I start worrying again
if there are reports of worn VCSs because of playing Star Raiders :-)
