Rich,
I don't know what Dad paid for the slip-stick. It was a gift, and I remember at the time it seemed like a pretty expensive item for a carpenter to be buying for his son. It is a model 4081-3.

They still had one of those vacuum tube monsters at Ft. Bliss, TX, in the early 60s. I remember it taking up several rooms, and we programmed it by flipping bit switces on the front panel and entering each instruction one at a time.

i really understood all the things they could do....

i also remember in 1961, some fellow coming to our Humble Oil office in Tyler, Texas and showing us a storage device which would eliminate all our filing cabinets. thank god we waited a year or two before expanding our use of the "new technology"

incidentally, my first handheld calculator was in 1970, cost $86.00 and would do FOUR functions.....
still got it and it still works fine....
