I am an electronic hobbyist. Got my oscilloscope, signal generator and I restore older HP calculators, LED and LCD types along with vintage tube 50's and transistor radios. In fact, I am writing a book on the "restoration of HP calculators from 1970 to 2000.
Came across this posting and have a question. What is the code for that Markus has included. Examining it suggests that maybe I need to program the M430G2xxx. This doesn't appear to be a pic chip. Does it fire up in the clock projects is, pre loaded as a ROM.
The question is, if I assemble the clock as described is the IC already coded for this project?
