Would some of the old time HP users out there help me fill in a few of the gaps in my knowledge of past HP calculators ? In particular, I'd like to be able to differentiate some of the members of the Top Cat, Spice and Woodstock series. Here's what I know and don't know: Top Cat series: 91 ?? 92 ?? 97 programmable scientific desktop with printer (cousin to 67) Woodstock series: 21 simple scientific 22 ?? 25 scientific programmable (a 21 w/program mode) 25C a 25 with continuous memory 27 ?? 29C ?? Spice series: 31E ?? 32E scientific w/metric conversions - non programmable 33E ?? 34C scientific programmable (like 32E but w/programs and w/o metric) 37E ?? 38C ?? 38E ?? Any thing you can tell me about the missing members would be welcomed. Thanks, Bob Armstrong

Let's see if we can fill in all the gaps:
HP91 - scientific nonprogrammable machine in hp97-like case. LED display
and printer. (Fairly close to the HP45/55 in power)
HP92 - business nonprogrammable machine in same case. LED display and
printer. All functions of the HP80 and more.
HP22 - "Woodstock" series business calculator. Not quite all the functions
of the HP80.
HP27 - "Woodstock" series machine (nonprogrammable) with HP25-like
scientific functions, HP22 business functions plus statistics.
Very similar to the HP27S in concept - a little of everything.
(Perhaps that's why its codename was "salad")
HP29C - "Woodstock" series programmable with 210 lines, partitionable
at 7 lines/data register into 30 registers. LED display. Program
compatible with the HP19C printing handheld (which fit in the old
HP10A case)
HP31E - Non programmable in the "Spice series" case. LED display, 4 data
registers....replaced the HP21 as the entry-level scientific.
HP33E - Spice series machine which replaced the HP25A/C. Also HP33C with
continuous memory. 49 steps/ 8 registers.
HP37E - Spice series nonprogrammable financial machine to replace the
HP22. 7 registers.
HP38E/C - Spice series programmable financial. up to 99 steps, up to 20
data registers. This was the precursor to the HP12C.
Okay...how did I do?

(My first HP was a 29C. I still regret selling it in order to buy a 41C: not that I could have done without the 41, but I could've sold something less important, like my sister into slavery or something ...) -- Tapani Tarvainen (tarvaine@jyu.fi, tarvainen@finjyu.bitnet)

The hp38c used an led display, had a little over 100 lines of program space, and about 15 registers. It was sold in the late 70's, early 80's. I owned one before switching to my STILL RUNNING GREAT hp41cv. The hp67 and 97 were the predecessors to the hp41 series. The 67 was a powerful handheld with a built in card reader, and the 97 was identical except it also had a printer, and was considerably larger. They also used the power-hungry LED displays. allen ifaq570@cc.Utexas.edy
