The chances are that it will run without any modification.  The only real
problem could be the top 16 bytes of memory banks 1,2 and 3 as they overlap
the top 16 bytes of bank 0.  I am in the process of converting a very full
16C74 using almost all of the peripherals, to a 16F877 and the memory
overlap is by far my biggest problem as I make extensive use of indirect
addressing.

Subject: [pic]:Moving serial routines from 16c74A to 16F877


Gentlebeings:

I am about to move some code originally written (not by me)
for a 16C74A to a 16F877.  Are there any 'gotchas' to watch
out for?  I am particularly concerned about the serial
routines possibly being different. There's about 3K of code
there, and memory banking appears to be correctly
implemented.
Thanks,
Alice
