HP 12C Speed Test

[E.J.E.]

Considering that ‘2-liner’ loop:
1; Enter; Enter; Enter;
01 +
02. GoTo.01
and some results by:

1985 12C: 499
1992 12C: 518
2003 12C (1x2032): 511
Early (silver, no undo) 12CP: 3150
Later (silver, w/ undo) 12CP: 1424
25th Ann 12CP: 1446
30th Ann 12C: 72,684
HP-25C: 535

I tested some of my HP 12C calculators:
HP 12C (sn 3534S03xxx Singapore, 3x LR44 CPU HP 1RR2-0001) = 507/min
HP 12C (1x CR2032 - CPU Agilent 2AF1-0002) = 534/min
HP 12C Prestige (sn CNA 6430xxx Brazil =CP; 1x CR2023 - CPU epoxi_on_pcb “BF123-11-3”) = 1458/min
HP 12C + (sn CNA 1410Pxx; 2x CR2032 - didn’t need to open; CPU not checked) = 80260/min

And for other HP machines or RPN based, using << LBL 0; +; GoTo 0 >>
HP 15C (sn 2826B31xxx Brazil, 3x LR44, CPU & IC: 1LH1-0302 & 1LQ9-0325) = 303/min
HP 42S (sn 3022B77xxx) = 2196/min
HP 35s (sn CNA 9320xxxx;) = 2801/min
WP 34S (from HP 20b sn CNG82801xxx) = 134702/min (2245/sec)
DM 42S (sn 8680; default mode) = 374799/min (6247/sec)

Finally, using the Hardware-based SUM function (inf: 1; sup: Y ; func: 1) on some popular Scientific calculators, just to provide a loose comparative figure:
Sharp EL-W516X (Y = 5000) @ 38sec = 7890/min
Casio FX-115ES (Y = 5000) @ 42sec = 7140/min
Casio FX-991LAX (Y = 30000) @ 52sec = 34600/min
Casio FX-991ES+ 2nd.Ed. (Y = 10000) @ 28sec = 21400/min

Untested (yet): I have a HP 20b unmodified and a HP 17bii+, which I didn’t think how to compare with this simple loop, in a fair way. Suggestions are appreciated.
I have an HP 41CV, but without batteries to test.
I and one HP48G+ and two HP 50G, but didn’t test them as they are much more powerful and RPL, (another class of HW) and looping could be implemented on different ways; however, if you suggest some reference program/function to check, I would supplement the testing info.

In overall, it was fun to test.
