Hi,
I have an old PCB containing an 80C552 with associated software (about 16K) in EPROM.
The manufacturer has gone bust and I am trying to
rebuild the system using another processor, probably a philips or cygnal.
The board operates a heating and cooling system and although I have a good idea of its operation, I would like to use the routines in the Eprom.
I have studied the disassembly and most of it makes sense, but I havent the time to do it completely.
I can write the new software, but a good commented disassembly is what I need. I can give a good explanation of how the board works.

I am quite prepared to pay for someone to look at this
and give me a quote - any takers?
Chris
