I believe you. And the "mystery" of your longer execution time can be explained, easily. Check carefully :-)

Quote:I have frequently used the prog "FAST" on the version A machine, but these tests were carried out in the standard state, ie "FAST" was not operating.

Can repeated use of "FAST" have some permanent effect?

Gerald, your version A machine execution time is normal, see my tests. It's your version C machine execution time that is longer. Check it :-)
Hint: I didn't say that your version C machine is slower.

New test of 11th repunit on HP 42S 3123S01777, version C, confirms your suspicion - time taken was 428s.

I don't understand the hint - 3144S06635 must be much slower in execution, implying the machine IS slower.
