Roger, Ah, the joys of a TI 59! I spent hours programming the beast to reduce my data when I was in Antarctica in 1980. I thought it was wonderful. Eventually I gave it away complete with all the modules, the mag cards, the programs and the manuals to a guy who collects them. I hope it is a good home.
Slide rules. Yep, I still have mine. Have you ever looked at Bion "Mathematical instruments" printed in about 1700. Rita Shenton sells it. Persuade your family to buy it for your birthday. Gives you instructions on how to make just about every form of instrument, including slide rules. Great book. HUGE book! Almost A3 in size, and about 2" thick. Just the job for accompanying your wee dram! John PS: A flash thought just before I hit the "send" button: GPSs have no SOUL. They have no connection with anything other than the US military. (No, I am not deriding the US or any other military). Thus there is no connection with the cosmos other than a hunk of metal hanging in the sky. Not terribly romantic, but highly accurate. Yeah, well I also like soul! I suspect that is a feeling with most of us on the list.
