Old computers... I mean
really old computers, before electronics. As many of my readers know, I collect old computing instruments – slide rules (especially), sector rules, Gunter's rules, and abaci. But there's one old computing instrument that I don't have even a single example of, and I'd sure love to:
Napier's bones. I'm not interested in any of the modern replicas; I would like to get one of the real deals, in any of
its many variants, made (most likely) in the 1600s. I've never seen one for sale, dang it. Anybody got a set lying about?
