I have 5 or 6 different PIC hex files that I routinely use on a moments notice, and having a painless way to choose and program chips would be a time saver. I also like Rob Severson's idea about making it daisy-chain-able. The two biggest problems I can see are hex file storage and socketing for 8-, 18-, 28-, and 40-pin chips. Assuming you are using I2C EEPROMs for storage, you'll need a very large one to make this whole idea attractive. And the multi-pinout socket problem is always problematical. =================== James Newton wrote: >I'd be interested in having some minor ability to stimulate a target circuit >(function generator, etc..) and read voltages and signals from it (DVM, >'scope, logic analyzer, frequency counter).

Tony, it would always be great if you could program a chip and "immediately" test it, especially in a completely automated fashion, but ....... let's make a guess about relatively amount of work involved: Your idea, work = 100%, add in the second "minor" test capability, bump up work by 400%, and increase pcb real estate and product cost by 250%. Make testing fully automated, increase work by 1000%. Been there, done that.
