Me again; I just came back to the C128 (still running the program) after
composing the last mail and the MSB was down to 28. Probably due to the
8502 warming up and the depletion mode pullup transistors decreasing in
resistance due to temperature. Time to try a real C64 and C64C.
Fascinating stuff!
