I have a unit with no directions or instructions. Does anyone know how this was/is programmed? Do you recognize the collection of programs installed now? I have a list of programs and functions in it now. 'PROGRAMS are written in user code, and FUNCTIONS are written in mcode. I also have three pictures of it. The locations were determined using the CCD Modules CAT function.
