Hi, sorry. It is not possible to program 16C715 with it. Why? Because of 16C715 is a very strange animal: it stores all codewords on 16 bits instead of 14 and the 2 bits are checksums. I recommend the programmer & software of Bojan Dobaj. I use it with success. Imre On Fri, 25 Dec 1998, Al Williams wrote: > Ok, I give... can I program a 16C715 with the Parallax programmer?
