Scot; If you mean serial to the pic but controled from a parallel port then check microchip's AN589. I have my own quickbasic and executables available if you do this. I used to run from DOS but now run from win3.11 when picstart+ gives me hassles(ie pic16c74). if you have a fast PC you can reduce the program time for each location which gives faster erase than the official pgm algorithm. My program includes a cursor selection of *.hex files a spare printer port comes in handy for low budget logic analyser tasks. regards, Graham Daniel -- I invent therefore I am.

I checked out a few sites with inof onn the AN589...it doesn't look like it'll do the 12C508, which is what I want to play with. Actually, I don't care if it's off the serial port or parallel, as long as it works :) Have you managed to get the AN589 to program 12C508's ?? Thanks. Scott.

I have successfully built and used the circuit shown in this link for both the 16C84 and the 12C508. It is self powered from the RS232 port. http://www.gbar.dtu.dk/~c888600/newpic.htm I have an epcprox pcb file for it some where if you are interested. regards Stuart. {Original Message removed}

The program algorithm is slightly different and the hardware only requires rerouting to the new pin positions, I DO program 12C508 with it regards, Graham Daniel. > > Thanks. > Scott.

OK, thanks Graham.
