So glad somebody remembers the comptometer!
Like I said granddaughter was amazed.
Remember the Bomar brain?
Yeah my company, Webster Electric, part of AT&T, knew they had toget away from comptometer sand I was the first to get a calculater! Indeed it cost over a thousand bucks per my aging memory!,
Funny met someone whoknows a comptometer!
And then a professor did a deal with Wang and we got some of their early models with Nixie tubes and card reader for programming
I used to borrow one of these from the company accounting office to do my numerical methods homework assignments.
