|  Re: Plus/4 Expansion port...
I have a quick question...After reading through this some of the pins marked as "outputs" are obviously not JUST outputs. The data lines for example MUST allow input as well since you can plug cartrideges in the back and it has to get the data back from there.
So what else isn't "just" an output? Is it only the lines marked "output only"?
Does this mean some lines like the ROM select can be altered via the port?
