Ahhhh finding one of these brought back some memories!
The Dalton Computer Dead Reckoning 4A Ref. 6B/2645 originally designed in the 1950s. I'm sure our had slower speed sliders ie that didn't go to 800mph? But my memory is fuzzy.
I could get a fixed depart out in less than 2 minutes.
Those were the days!
