Q1. Is it possible to extract program code from a 12F629, or does it have a
security link?

Maybe, and yes.

Q2. How compatible are the 12F629 & PIC16C56 in terms of command set?

The 14-bit 12F629 instruction set is a superset of the 12-bit C56 set.
It has better hardware on-chip as well (relatively speaking).

Q3. How compatible are the 12F629 and PIC16C56 in terms of functionality,
specifically, is the 16C56 able to do everything the other can?

No, the 16C56 has no interrupts, for example, so there are MANY cases
where the cheap-ass C56 cannot replace the F629. Depends how much
effort you want to put into the programming too.

Thanks in advance.
