Anybody ever use one of these? Some of you more sesoned aviation types may remember them being used for navigational calculations in military aircraft.

When I started my articles, these were still in use! I coudl manage a fair turn of speed on them when it came to adding up columns and columns of figures!

I remember my Dad having one and teaching me to use it.

An absolute jewel.

Believe they go for big money these days if you can find one.

:ok:

Edit: Checked: between $230 and $800 on eBay - only a few going.

Aaaaaaaaaaaaaaaargh!

Had it installed on a dashboard of my rally car, before I had the Curta. All my buddies made fun of me saying: "that's the guy with a cash register in his car. If the navigator makes a mistake he charges him."

...And here's a few "computers" that we still have to use; in theory, if not real life thankfully!
