i'm SORRY i'll think next time before asking a question that may be met with pedantic remarks about assembly fundamentals it's just that with all the addressing modes of the 6502, it's hard to remember exactly what's allowed. one might conclude that since when x=3, LDA $0303,x means LDA $0306, maybe...

also, is it possible to use a 8KB or smaller ROM as a PRG? iirc, all that's necessary is to tie certain address pins high or low, ok i forget. You can, but there are no commercial games that will fit -- the smallest is 16kB. You'll need to use two and some external logic. Address lines generally do...

Note, however, that a 2764 is only 64kilobit, or 8kilobyte: It would take 3 or 5 to support the tiniest of NES games. They would be far more practical for making Atari 2600 repros. Or NROM CHR ROMs, if you can dumpster-dive a bunch of 27C128 or 27C256 parts to use for the PRG. thanks, Tepples. you ...

It can program most memory chips like EPROM and Flash, and some microcontrollers. It didn't program the PIC I was using, so I had to get another programmer to use with MPLAB. And it can't burn any PLDs. If all you need is memory chips and maybe a microcontroller, it should be enough. for now i'm ok...

Willem.org : "caveat emptor"
I'm in the market for an EPROM burner and as directed here, i went to www.willem.org and Sivava. Willem seems to be plastered with messages from angry customers that they never received their orders. And Sivava won't return my email questions about products and shipping. Any corroboration on whether...
