Yes, I created a paddleboard with a PIC16F876A on it to emulate a 
PIC16F627/-628/-648
project, but in fact, it will emulate almost every PIC16 with that same 
MCLR/VDD/GND wiring
setup (PIC16F818/819/54/84, etc etc). The paddleboard plugs in where the 
PIC16???? did.
Very slick, I used the ICD2 to debug the code.
