I have made a lot of progress. I can load the internal 4KB SRAM with a small loader procedure. I can get the loader to read the EPROM, modify code space via code/data over lay, and reset via the WatchDog. Now comes what maybe the most difficult part.

I need to create an EPROM loadable hex file containing both my RAM Loader and the application software. I want to take the application as is and load it into RAM at the correct address.

Does anyone know of an easy way to combine two separate programs into one loadable image? I suppose I could do this by hand, but I'd like to spare myself that pain by creating a project that will build the final loadable image for me.
