I loved calculators but I actually rarely need them. I've stopped
buying them. But not before I bought too many.
The first calculator I bought was a used Sinclair. You, Stewart, will
know of those. Amazing but very cheaply built. It didn't last and I
no longer have it.
My first calculator was a Rapidman 800, which sold for about $100 at
Eaton's, IIRC. My next one was a Novus Mathematician, which used RPN
and then a couple of Sharp calculators, the first of which used
batteries and the 2nd light powered. These days, I use an Android app
called RealCalc.
BTW, as I mentioned the other day, I still have a slide rule from my
high school days. It's a Pickett Microline 120 and it still works 56
years later! By the time I got to Ryerson, I was using a calculator.
