HP41CV or Calculators don't count do they ? I used to write programs for this calculator - hpmuseum.org Contrary to what you might think 319 registers are a lot if you are using Reverse Polish Notation. It took a little getting used to but once you got past that the calculator represented a huge step forward for anyone doing hard math or engineering. You couldn't drop it in a puddle, they were expensive, about the same cost of todays basic laptop, but they openend up several new areas for calculators. Programs were stored on little wrigley sticks of floppy material, cards and card readers are what they called them. You could get a range of expensive accessories but the only one I ever got was the card reader, I used it for storing programs. When you ran a program a little bird shape danced across the LCD to show it was "executing", programs could take several minutes to run. I eventually sold it at a garage sale for twenty bucks to some lady who was going to use for grocery shopping, I often wondered if she got her head around the RPN thing. Most calculators expect something like this 2+2-1=1, in RPN that is 2, enter, 2 enter, 1 enter, +, - (there is no equals key on the 41CV, the first clue that it is an RPN formatted calculator)
