Notes from Virtual Meeting 9th May 2020
The Canon X Pro Mk 1 that I showed ( https://www.amazon.co.uk/Canon-X-Mark-Pro-Calculator/dp/B00CXQ3AXI) is no longer available new. However Canon have what looks to be a functionally equivalent model, the F-789SGA https://store.canon.co.uk/canon-f-789sga/6467B001/?nav=calculators%2Cscientificcalculators.
The machine is not nearly so stylish but arguably looks more practical to use day-to-day. I'm sure it still has the vast range of physical constants so an ideal Top Trumps model to own.
Comments
BTW, if you search for "Curta by the dozen" you'll see some findings of mine. As of some time last year, I have held and ever so slightly used a Curta, but still haven't owned one.
I found a trove of links to handheld computing websites which might be of interest, particularly Ledudu's pocket computers looked good.
