RE: Which HP calculator had "The New Accuracy" first?
Hmm, I see that if we subtract the two powers instead of dividing them, we learn a little more:
HP-35 (v4 ROM) -7.96E88
HP-25C -7.96E88
HP-29C 5E86
HP-15C (LE) 2E86
HP 30b 2E84
HP 35s 2E84

Also, it occurred to me that if we're seeking families of machines which use the same algorithms and machinery, we should expect the calculator forensics test to produce a related grouping - perhaps a slightly coarser one. (Instead of measuring log and exp, we're measuring trig, so it might not be coarser, just different.)

From the results page:

9.004076901
HP-35v3

9.004076644
HP-45, HP-46, HP-65

9.004076898
HP-55

9.004076649
HP-21, HP-25, HP-25C

9.000417403
HP-27
HP-19C
HP-29C
HP-41C
HP-41CV
HP-67
HP-91
HP-97, HP-97S
HP-10C, HP-11C, HP-15C (Voyager)
HP-31E, HP-32E, HP-33E, HP-34C (Spice)
