hello,

i look at my desk ...

TI 30 galaxy solar calculator - bought in 1985 for high-school and still in use: maybe not daily, but at least once or twice a week :))

cheers v

ps. also a multimeter and a soldering-iron from the 2nd half of the 1980ties ...

A HP-42S and HP-19B my father gave me. So somewhere around 1980 and I still think these are the most awesome calculators. Still works like a charm and still in use weekly.

I'm so used to UPN that I always struggle to use a "regular" calculator.

hello,

yes ... the HP calculators where really great, but also prohibitively expensive ...

the TI 30 in all its variants was the "cheaper" scientific calculator for the masses in the 1980ties :))

cheers, v

Can't say how much they cost. They were built some years before I said hi to earth.

Edit: Prices seem to have increased and a 42S sales used on Ebay from $150-259. So still quite some money.
