I hope this isn't a bad batch of 16F88's. I bought 50 of these, but it was back when they first came out, so maybe. If they don't work with the new compiler etc. then I will try them with a crystal, but that won't do me much good as the board they are going into has already been produced without a section for a crystal. You might be asking, "What kind of idiot gets a board produced without having fully tested the code in a microcontroller?". Well, the board is actually designed to use either a 12F683 (which it has been using for a couple years without any problems) or a 16F88. The 16F88 brings in some advanced circuitry and options to the circuit that we haven't used up until this time, but we would like to start including those options. So, I am stuck with needing to use the internal oscillator since that is what the board is designed to use.

Are you aware of a bad lot/date code of 16F88's?

Thanks for your input!
