Thanks Steve, that was my reading of the Microchip guidance but the 16F84A is very expensive here so didn't want to go ahead without being certain.

Guess I really ought to get to grips with MPLAB to learn how to convert .hex to .asm - so far I have stuck with MCSP - it seemed less daunting! It would make financial sense to use the 628.

from the .HEX, you can create the .ASM and then modify it for the 16F628.
