Not being tribal here, as you can probably tell from previous posts of mine in this thread, I have little to no time for tribalism.

I think it's fair to say if there's one time when Dr Kahan's knowledge gave HP the edge, was from the mid seventies till the mid eighties.

I'll rephrase my original comment to any decent calculator released in the last 20 years or so should resolve to 1. Certainly any I tested from that timeframe resolved to 1 (TI, Casio and HP, in fact most went back far more than 20 years but I thought I'd err on the side of caution).

I completely agree. Actually I own the HP-67/97/41/15c from that era.

Interestingly, Free 42 / 42S, and presumably DM42, do not resolve to 1 (They resolve to 1 + 1E-33).
