Peculiar speed differences between two 11Cs

[Marcovecchio]

This page lists various chip versions for the Voyagers during production years. I think you can open your calculators and easily check the chip serials: http://www.brouhaha.com/~eric/hpcalc/voy...iants.html

Perhaps we can find a relationship between revisions and performance. I have about 6 HP11c calculators, from various revisions. If you share your tests, times and chip revisions, I can test here and share my results to help find a pattern.
