Basic Stamp Question

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.

The stamp is interpreted in the PIC as far as I know.
this means, there is a base program in the PIC that is
reading your stamp program. (BASIC) most likely.

It's the slow way out and limited how ever, for basic (Very basic)
it's fine and having all the components on a ready made module is nice.
I do think you can rewrite the boot loader and use your own asm/C code
from start in the processor.
