Is the PIC16C57C-20/PIC16C57 in the Basic Stamp 2 the same as any
other PIC16C57C-20? Or is its ROM programmed in some way to interpret
PBASIC code?

Thanks,

The OTP ROM is programmed with a token intepreter. It cannot be
reprogrammed. The tokens are stored in an external serial EEPROM. The
PC software converts the BASIC program into tokens, which are then
downloaded and stored in the SEEPROM.

An unprogrammed MCU will not work. You can probably buy chips with
their proprietary program from the maker (Parallax?). Naturally, they
will have protected their program so you cannot simply copy it.
