Most common calculators in the forum?

[TheKaneB]

Here it is my list

HP
12C (original version, it sparked my interest in financial calculations)
15C (bad conditions, but my favourite one nonetheless!)
35S (not as bad as many users think, I like the solver)
28C
50G (THE calculator IMHO)
Prime (a gift from my girlfriend!)
30B (soon)
48S (dead)

CASIO
fx-82MS
fx-991ES Plus (very nice basic calculator)

SHARP
EL-540
EL-5120 Solver (my first scientific calculator, I got it 2 decades ago and started my interest in calculators and math)
EL-9900 (was very nice, but dead display after a few months, don't touch it)
ELW506 (the keyboard is garbage, but a nice basic calculator otherwise)

TEXAS
TI-89 (the display is poor, but I like the programming model)
Voyage 200 (very nice for programming)
TI-92 (dead)

I'd like to get some Casio and TI graphing calculators, and also some HP pioneer series (the 42S looks amazing but it's really expensive in my area).

HP 9825B (doesn't work, but it's a 9825 so I'm still counting it)
HP Prime

TI-55

Jeppesen TechStar
Radio Shack EC-281
Radio Shack EC-450 (rebranded Bowmar MX100)

Royal 91S

I excluded handheld computers, four bangers, mechanical calculators, slide rules, abacuses and inventory items. The only calculator I keep in my desk drawer is a K&E 4083-3, and my EDC is an early model Pickett N600-ES with a CIF scale. I have several HP emulators installed on my computer, but Emu48 definitely gets used the most.

You should probably lump the SR-40 in with the original TI-30, as they are exactly identical except for the location of the key labels (on keys vs. on bezel.) They were even introduced on the same day. TI apparently felt that double-shot keys justified a doubling of the initial list price, from $25 for the TI-30 to $50 for the SR-40.

Hmm, enough new entries. Time for the next update. As soon as I have time today (or tomorrow) I will do it.

Had a 41 CV, printer, wand got rid of it all :-{

I've just updated my initial post with 8 new machines acquired over the past few weeks, namely:

Texas Instruments: TI-66, TI-80, TI-82

Casio fx-570, fx-1000F, fx-3600P, fx-3650PII, fx-6500G

Very pleased to get the rare fx-6500G as I now have all three major players in that family of machines (6500G, 7000G, 8500G). Not so interested in the 8000G because it's basically a watered down 8500G but if I do see one going cheap I'll grab it. The 7500G clamshell thingy? Meh...

I'm updating also my first post, as I got a Casio FC 1000 (financial consultant) and they are coming here (next week) HP 41CX and HP 42s (happy!).

Happy HP New Year!

Hello,

some recent additions from me as well (mostly non-HP I am afraid):

-> HP-25 (working)
-> HP-14B (working, this must be my first "normal" 14B, I already had 2x the anniversary model)
-> Ti-83+ (2x)
-> Ti-84+
-> Ti-89 Titanium (no.2 for me beside a non-titanium Ti-89)
-> Casio FX-880P "Scientific Library" (that's a real powerful little pocket computer which would deserve a writeup on it's own)
-> Lexon "Rulercal"
-> BWK Business (I always thought this to be a kind of German clone of the HP-12C but now I know it isn't - among other things one can connect it to a PC via USB and use it as numeric keypad)
-> Privileg 585 D-E-NC (green VFD scientific, working, the original NiCd battery even holds it's charge)
-> Airtour CRP-1 (circular slide rule for aviation)

Very true. I have one of those myself. Bought it new when it first came out, so that's a good few years ago

The BASIC interpreter is quite fast for a machine of this one's age and I like the way you can treat the databank a bit like a sequential file.

There is also the 6000G => http://www.emmella.fr/collection/CASIO-FX-6000G-001.jpg

En effet, je l'avais oubliée, celle-là, mais je crois qu'elle est aussi rare que la 6500G, sinon encore plus rare !

And of course, on my desk with my best slide rules is my dad's mint, working HP 35 from 1973!

[EdS2]

A recent addition to my collection, received as a seasonal gift: a Sperry Remington 661D - 6 digits displayed, up to 12 calculated, fixed point. From 1972 or so, actually made by Casio, and with a Hitachi chip.

I came across a Sperry-Remingdon 663 at a thrift store just a couple weeks ago. It's virtually identical to the 661-D, but moves the power switch from the front face to the side.

It's a bit hard to find, but if you like weird Casio Mini adaptations, I recommend the Root-8S.

I edited again my first post, as I retrieved in my mother's cellar my old Casio PB-110 (Database Computer and calculator), 1983 (described here).
I must only change the two CR2032, Tuesday...

1 x 15c (died spontaneously last year. Didn't know they could do that.)
