I notice that you changed the 18F452 to an 18F4520 at some point. Are these interchangeable on the early PCB (when we were making our own) or do they need the latest PCB?
The 4520 is a direct replacement for the 452 so you should just be able to swap them.

The firmware has been fairly stable for a number of years now, most changes have been fixing edge case bugs or minor changes to deal with the way people use the controller so generally if it works I wouldn't bother changing it.
(My main indexer still has V1.2 in it! I do keep meaning to swap it but there's never been a need.)
