I've been planning to learn PIC assembly for a while now.. The roommate > keeps telling me I'm wasting my time with all this 6502 stuff... Don't listen to them!!!! The 6502 rules all! (Ok...the 6809 rules all, but hey! :) The PIC is useful, but you can learn to use them in an afternoon. After that, where is the fun? The only challenge is finding a project to work on. You'll never run out of challenge trying to write for the 2600. :P But when I say programmable logic, I don't mean MCU or MPU. I mean PLDs and the like. With a 20MHz PIC, you only get an instruction every 200ns. That's fast enough for something like this, but it's pushing it. PLDs can be had with ahhh..."response times" of < 5ns. (I'm grouping everything into a generic "response" that basically has no real meaning.) And they're cheap. Sorta. > We should be starting on the 8k bankswitched version pretty soon. I remember > getting those 13-input AND gates and wondering, `wtf would this ever be good > for?', now I know :) Yep...address decoding. Take a look at an old ISA card for the PC. You'll most likely find a 74133 hidden someplace. - Archives (includes files) at http://www.biglist.com/lists/stella/archives/ Unsub & more at http://www.biglist.com/lists/stella/
