But I *DO* remember that I enjoy playing with HP calculators, so at least I still have that.

Don't worry Joe, +1 even if I'm just a bit younger...

Yes, me too, and I'm not 60 yet.

I just tried the 29C in emulation and was surprised to see a different answer - was there another change in HP's arithmetic?

Here are my results:
HP-25: -9.99E-08 (same as emulated HP-35 with V4 ROM)

HP-67: 1E-09 (microcode emulation)
HP 29C: 1E-09 (microcode emulation)

HP 35s: zero
HP 30b: zero
HP-15C LE: zero

(I think the LE uses the same algorithms as the original 15C)
