The bulk of the code is in assembler with the user interface written in PBPro. The client wants to add extra features and functions to the existing code base. In doing so I will exceeded the memory capacity of the 877A. I am looking at the 18F4520 as a replacement. The portions written in PBPro are easy to migrate but about 75% of the code is in assembler (although well documented). Aside from jumping in head first and going blind into the project are there any issues or pointers that would make life a whole lot simpler that I should look at before I proceed. Thanks all.
