I still have my Dad's old rule, made of bamboo with an ivory veneer. I believe they came in three qualities back then, all bamboo, ivory veneer (as the one I have), and all ivory. The slides are celluloid, and have to be protected from sunlight.
I have no idea about that. I have three or four, all inherited from an uncle and from my father, all used professionally. I think they are made from ivory, but I can't certify it and I'm not disassembling them to know!
My times at school were of paper and the beginning of calculators, which were very expensive back then in Spain. Four rules and bigger than a cigarette package, with some kind of fluorescent display.
No, no linux on them, I'm afraid - just to stay on topic briefly ;-)
I guess, as the fomenter of this thread--which has gotten even further OT than I ever thought--I could contribute this: I have a Lafayette Radio Log-Log-Decitrig rule, model F341, made in Japan, in perfect condition, which I used to use in the 1960's and early 70's, until calculators became available. I think it is made of bamboo, but it has a very nice plastic scale on both sides and the slide. I admit that I never understood all the possibilities of this fine instrument. It works as well today as it did when it was made. I don't! --doug --------------------------------------------------------------------- To unsubscribe, e-mail: opensuse+unsubscribe@opensuse.org For additional commands, e-mail: opensuse+help@opensuse.org
