The 10s and s+ have several keys swapped around from the FX82/85MS layout; arrow keys match the 48family more closely; the x^3, a/b/c, square root and some other keys moved around, so there must have been some work done on the keyboard matrix at least for HP. The only other difference I can see for the 10s+ is a slightly different colour scheme. Under certain lights, I suspect that'll be harder to read the llight blue. My only experience with the HP10s was a bad model, as several lines of dots from the top line disappeared, otherwise I would have kept it, and it would have cost me more money to send back to the retailer for a refund. The laugh is, I'd been prompted to buy the calculator because the listing showed 128kb of memory. Clearly most of that memory wasn't accessible for programming, and indeed the calculator isn't programmable. I have my doubts about whether the 128kb of memory figure was correct, even considering that some memory would have been set aside for statistics variables and regression calculations.

They will have got Casio to make a few alterations to the ROM. But here's one change they didn't get Casio to make (very likely an oversight): https://www.youtube.com/watch?v=4F873zbyM8

Here's a weird thing. Multiple people indicate that they have that contrast setting on their calculator; either it's hidden (but is working), or it shows up and is working. My FX82MS doesn't show that contrast setting, nor does hitting the "2" key at the right place trigger a setting for contrast. I'm not sure if they customise them by country. I couldn't exactly say what date I bought it either, just that it was several years after I'd got my 82TL. The date code on my circuit board says 02094, the main board identifier reads GY3131, so I'm guessing it's the first revision. Another identifier on the board: HA210314A2. Hardware hacking the calculator? Hm. There's four places to put more capacitors, but no capacitors in those positions nor (mostly) lands to solder them to. At least this post should probably have been in "Not Remotely HP", due to its drift from the original subject of "most common calculator". Let's get it somewhat back on track. Currently in NZ, the most common calculator in a kid's home will either be some variant of FX82 such as the ES Plus, AU Plus or descendants thereof, or if they're in the last years of their schooling, it would be the 9750gII. After they finish school, you can often find their calculators on Trademe (a NZbased auction site) for much less than the new calculator was originally bought for. I picked up my gII in just this way, as I really really didn't want to pay the new price of $154.95 (NZ dollars). (Post 230) Regards, BrickViking HP50g Casio fx9750G+ Casio fx9750GII (SH4a)

28S x 1
48SX x 1 That is all. I feel like a big fat phony 'enthusiast,' but as a student I can't really afford to start buying up all of the more expensive models. The 28S and 48SX appear to be some of the cheapest old HP calcs around, and I really like the 28S form factor in particular. I especially can't afford to buy more calculators after my car (a Volvo 240) got crunched and I had to foot the bill to fix it (hit and run).

RE: Most common calculators in the forum?
Not many, but use daily as tools.
HP16C (1985 manufactured) and a DM16CC as a backup, actually ordered a DM16L from a used store but they sent me the CC (Credit card version) and as it was only 30 Euros used I kept it, but quite hard to use daily, so sticking with the 16C. HP28S (1988 US model), DM41X (2020)

When I use them in a public place, many people look at them and some start a conversation about them. As for the TI 89 titaneum, you are correct in not counting it in your collection. I have one that is very useful as a paper weight or a door stop. Cheers JL

A true multipurpose machine :) And, I hardly dare say that on this forum, if I had to go back to university now I personally would take a Ti89 or Voyage200 rather than any calculator made by HP after 1980. And to complete this survey (and contribute to the statistics...) since I last answered this thread I have accumulated, among others, the following calculators: HP27 HP27s Elorg 51 HP41CV (yet another one) Ti59 (yet another one) Cateck Magic Keyboard and Calculator (very stylish and hard to find bluetooth keypad with large 12digit display  but four functions only.) Canon F61 Canon F71 HP25C (yet another one) 2xTamaya/Riefler Planix 7P (a digital planimeter, but it can be used as a standalone printing calculator and therefore counts as one in my eyes. This, by the way, would be the ideal paperweight/doorstopper!) Commodore N60 (my second one) Regards Max
