Some of the sites you refered me to also mention using the controller port although I've lost which sites exactly (just done a lot of reading) but I'm almost 100% sure that the control port is an I/O port (Input/Output) so it is possible to send stuff out aswell as in through it.
Trying to use some of the terminology there as you may have noticed
Looks like I've got a lot of reading ahead though since there is a lot of terms and visual aids I really don't understand.
I did have a wee chuckle at this line though:
"Now, as you've built this ROM copier, it might be a good idea to use it.
However, if you built this ROM copier purely so that you could burn yourself on the soldering iron, then you may skip this section."
Nice touch lol
I don't think Matttail is coming back so I'm jacking this thread and declaring it my own!
