Most common calculators in the forum?

[Maximilian Hohmann]

Hello!

And another entry into this thread which will shift the "most common" statistics a little bit away from HP products - as I have been unable to find any affordable ones for my collection during the last few weeks.

But I found (and/or was given) some other calculators worth mentioning and counting into the statistics:

A Ti-nspire, second version, with the exchangeable keyboard:


A holding pattern computer (which must be one of the most useless devices containing "computer" in their name ever made. ):


An Airtour CRP-1 circular slide rule navigation computer. Very substandard build quality, especially compared to the competition of Aristo.


An actual HP item, a 4k memory module for an HP-71B. Another module is still in the mail, a Navigation pack for the HP-41:


A little collection of banknote-calculators which must have been en vogue in the 1990ies if one can tell that from the currencies, some of which have been replaced by the Euro in the meantime:


And this is the calculator side of the 100DM banknote. Who has ever thought about Clara Schumann again after exchanging his last 100DM bill for 50 Euros?


A Ti-92plus. Big thing! I already have the non-plus Ti-92 and it's successor, the Voyage 200:


A Sharp PC-1403H. With a dedicated "Matrix" mode that must make it somewhat unique I guess:
