Most common calculators in the forum?

[DA74254]

Since I've got the tracking-number emailed from Steinmann, you may add the DM42 to my collection

Are they actually selling them now?

Yes, you can place an order on this page, the topmost item:

In the last 2 weeks - I added:
DM-42 - looking forward to it.
HP-21s - curious to see what an HP, non-RPN model is all about. Haven't used non-RPN in decades
TI SR-11 - found one for $10 on the 'bay. Switch issue, sprayed it with contact cleaner, now it works. This was the first calculator I had in college in 1974. Brings back many memories. The next calculator I bought was an HP-65! Spent almost a month's salary to buy it in 1976.

I'll add:
1x HP 48SX
1x HP 48GX
1x Renown Personal Calculator

[ttw]

Three working hp50g calculators for normal use.
One prime for destroying computers.
A couple of 41c types but no batteries (those little ones are too expensive.)
I think I've got a 49 somewhere and a 33s.
I think I've got something like a 16 or so for octal and hex math.

One of my employers was getting rid of all the calculators and just gave the used ones away. I did buy the hp50g versions as they are the most useful for math explorations.

When it was introduced in 1979, it instantly made all previous programmable calculators obsolete. The HP/TI rivalry ended in an instant and never really returned. And finally, by the time the 41 was superseded by the RPL calculators, PCs had become so cheap that they destroyed the largest market segment for programmable calculators, namely, people who needed something programmable but couldn't afford a computer.

That's how I remember it, anyway. Even though the 48 series were incredibly impressive machines, they never generated the kind of excitement that the 41 had.

You got it right Thomas.
The things that set apart the HP-41 was that is was a system, like Richard Nelson love to say.
You could add modules, peripherals, etc.
You could used it as a calculator, as a controller of electronic equipments, as a data collector in a surveying environment, etc.
It was a small instant on computer in a form of a calculator that you could customize it (software & hardware) on the fly to fit your need.
I have more than 25 x HP-41C/CV/CX/CL in my collection, including 6 x 41CL and 2 x 41CX halfnut that I still use everyday.

+1
Actually a system
And even the PCs have had so many dedicated peripherals and extensions
The PCs soon became fully equipped portable devices, integrated systems that just wait to be connected to the network,
But already the HP41 with HPIL thought in connecting the world!
This calculator is always alive and young and even has found a new soul and is certainly not shy if invited to dialogue and work together with modern PCs
For this reason is perhaps one the most beloved

Nice list! I added only the HP tough, it would have been too much to add everything. Sorry.

Feel free to pick some more items from non-HP brands but not all of them (unless you provide the first post edited, then I can just paste it there)

I have the feeling that the dm42 will raise quickly, and I am assuming that the bought items are working (thing that could be false, the dreaded "dead on arrival").

I am also slowly starting to see a pattern (yes, good morning Pier!).
S = scientific ?
G = graphing ?
B = business ?
E = Europe ?
C = sCrap? ( you mad?) . Jokes aside: compact? Commercial? (For) Companies?
A = Alpha ? (prototype?)

110 x 41 C/CX/CV
108 x 48G/GX/S/SX/G+
76 x 50g
64 x 12C/12C Platinum/12C 30th AE
49 x 15C / C+ / LE
41 x 71B
35 x Prime
34 x 35A/35S
30 x 32S/S II
28 x 75/75C/75D
26 x 42S
23 x 34S
21 x 25A/25C/25C/E

LOL

The 'C' stood for "Constant Memory" when it was first used. Back then, a calculator that didn't lose its memory when switched off was a rarity and it was something worth crowing about.

[pier4r]

Good to know, thanks! Are the other suffix correct or not? Especially E and A. Because B, G, S seems quite fitting the design of the device.

[grsbanks]

I honestly don't know about E and A but Scientific, Graphic and Business are correct as far as I know.

"Continuous Memory," actually: http://www.hpmuseum.org/3qs/25c3q.jpg

"Constant Memory" is how TI advertised the feature http://www.thimet.de/CalcCollection/Calc...-58C-M.JPG

I've never seen an explanation for the Spice series' E suffix. Given that being less expensive than their predecessors was their main selling point, maybe it stood for Economy?

Absolutely. My bad.

Thanks for the correction.

"E" was generally for Engineering (31E, 32E, 33E), though there are clearly exceptions as the 37E and 38E are both business models. I think "E" was only used for the non Continuous Memory Spice models, plus the 94E (here, E denoted memory size)

"A" was actually not officially used by HP for any model I'm aware of. However, when another model came out with the same model number and a new suffix letter, the original was often listed with an A.

For example the first HP-10 was simply called HP-10. But when they introduced the HP-10C, references to the original model were often stated as HP-10A.

Someone once showed me some HP literature where the A suffix was used, but I can't recall the model... Anyone??

HP-44A.

Then there's the 71B (Basic) and 75D (?)

Very good, thx Dave. You'd think I recall that...

Like most things with the portable computer models, none of the HP calculator rules applied. Perhaps these were in mind

75C - Probably for Continuous Memory - this was in '82, so shortly after the 41C and Voyagers, so still trendy
71B - It's Better than the 75C
75D - It's only slightly Different from the 75C; adds a wand socket and costs even more...

Mine is in the Pod, not so portable, then.
