I'm sure someone will correct me on this if I don't have my facts straight. This does not directly answer your question, but the oldest PIC16C84 MCUs in my PIC antique collection I have are marked 9411 (11th week of 1994). This does not mean that this date is when the first production parts were released however -- it could have been much earlier in time. In addition, these are not engineering samples -- engineering samples would have been released before production parts. Unfortunately, I do not have engineering samples (ES) of the PIC16C84 to check their dates. Have you checked the Microchip press release archives on their web site? It's a great and fun place to look through the history of Microchip.
