Yes, thanks for remembering that. Originally I wanted to use the method to
distinguish 6510 and 85xx CPUs (the time differs between them), but then you
found that the value depends a lot on the temperature as well, even more than
on the CPU type.
I wondering what A.K.'s part is in the story, he jumps into every discussion
that is about CPUs and shares his "secret knowledge", as if it would be the
biggest achievement in CBM history ever. Rather annoying ...
