You might be able to get something like a simple DPC woking with a PIC. But it's not worth it at this point. Best to start with the basics anyway. > Hrm, but it would be cool to put a POKEY or something inside a 2600 cart, > if only there were a way to get the audio from it to the TV speaker.

Might add some RAM while you're at it :) Heh... #69 on my VCS Project list: get video ram working. Audio would be much simpler, of course. > I'm not familiar with these PLDs... what's a good example of this kind of > chip? Try doing a Google search for "palce22v10 datasheet".

But really, all you need is 2 8-bit registers and a quad 2-to-1 mux chip to build a parallel port cart dumper. And the cart port of course. Then it just becomes an exercise in writing QBasic drivers. ^_^ -Chris - Archives (includes files) at http://www.biglist.com/lists/stella/archives/ Unsub & more at http://www.biglist.com/lists/stella/
