Speaking of which, I have quite the collection of parallel printer cards I could let you have for a meager fee if you'd like to reverse engineer them, or perhaps let you have them to reverse engineer on loan so I could have schematics so I can mod them into dual direction cards. One or two of them might already be dual direction compatible. I'm not sure. Would be nice to be able to use them to pass data between it and a ECP or ECP port on PC.
If the card has a 6522 or 6820 on it, then it has a good chance of being used bidirectionally. The problem isn't making a connection "hardware possible". The problem is making a convenient data transfer "software possible". ;-) Anyone who is serious about writing the Apple and PC code required to do this will find that reverse-engineering a parallel card is the least of their worries. -michael New Applesoft BASIC interface for NadaNet networking!
