Oops, left it off the list, but I indeed have one. The computer part works, but the printer is majorly messed up. The daisywheel carriage constantly seeks to the right, making a lovely racket when it rapidly bangs up against the end of its travel. Truly a disgrace to my good(?) name.

This was the only desk top calculator in a lab of 60 engineers when I started working there in 1972. It sat on a trolley with a little flag on a telescopic aerial so you could spot who had it in the open plan maze.

Lucky you! I'd love to find a HP 9100A/B. So far, I've amassed a bunch of HP's pocket calculators, including a nice example of the HP-35. Amazing how far they were able to come in four years, squeezing (most of) the power of a scientific desktop calculator into something which fit in Bill Hewlett's pocket.



More of these can be seen on my calculator page.
