I had an idea, to use a 16f876 for a device which would have modules to = plug onto it with eeproms with code that the 876 loads for that specific = module. So using one pic and a few eeproms and sockets, you could = conceivably, have a programmer for any chip, or a logic analyzer or = whatever. I was also debating that if anyone would build it, or if i could sell it = as a commercial product. thanks andy n1yew -- http://www.piclist.com hint: The PICList is archived three different ways.
