An interesting article :
http://www.theatlantic.com/technology/archive/2011/08/what-your-old-graphin…
My _old_ graphing calcualtor is an HP9100B with an HP9125A plotter. Still
works fine, although I did have to reqwind both motors in the plotter and
do some minor electronic repairs to both untis.
My moder modern graphing calcualtors include an HP28C, HP48SX, HP48GX and
HP49G. I've not used the 28C fro some time, but I use at least one of the
otehrs almost every day (admittedly not necessarily for graphing a
function).
Actuially, I am saddened that the above article doens't metnion HP
machines at all. Once you've learnt RPN, you newver want to go back :-)
