I just noticed that this is a 7501R1 (0184) whereas my early C16 > has a 7501 (5283) I wonder if they're different? Later chips had a 'R0' on them if they are the first silicon, maybe MOS didn't do that at that time. It would still indicate that the 7501R1 has some subtle changes to the older 7501. Did you measure the current they draw? I remember my 7501R1 drawing 20mA less than the 8501R1 and 8501R4 I have.
