HP-41C List of "over 130 functions"?
A curiosity of mine has been finding an official list of the "over 130 functions" that HP advertised in the early days of the HP-41C. Early advertising materials and the original handbook (dated January, 1979) references multiple times the 'over 130' number, and the handbook has a supposedly comprehensive list of every HP-41C function, but that list is only 129 entries long, and one of them is an error (a repeat), so that list is really only 128 long. I have not been able to find a list from HP that has more than that. Has anyone seen one? Was the >130 number created during the design of the HP-41C before coding was complete, and upon actual release, some envisioned functions had to be left out? Later advertising materials used a different number. I remember one catalog saying "more than 127 functions", which strongly suggests 128 was the specific number.
