I've still got my Abacus and 'Slip Stick', Log Log Decitrig (sp), that
I can use when the energy runs out and we go back to the caves and
bear skins. Still have the instruction book to refresh operations. G

I take out every few years and run the slide to keep smooth for
precision operation.

Kids. Bah humbug. I have one of those fancy new fangled slip-sticks, too.
I'm trying to find some Napier's bones and an abacus however.
