Re: Hot Pies
Marchants...a voice from the past. And Brunsvigas. I remember using them in 6th form statistics. It was kind of having a big geek secret. Working out square roots (for standard deviations) using Newton's method.
At university there was a 4-function electronic calculator. Chained to the desk.
Ten years later, working with a small rack containing 3 16 bit microprocessors and high speed interconnects.
And you know what?
None of them had failed keyboards or overheating batteries.
