I considered buying 'em for parts and art projects, but while I'd part with a couple hundred dollars for 'em, a couple hundred MORE for shipping makes it beyond the "that would be nice to have" category. > Of particular interest, as I'm in the throes of designing a simple analogue > computer. I've been considering doing the same. Op-amps are cheap and common these days, and it would be nice to build an analogue chaos machine (the original research on chaotic systems grew out of a weather simulator on a Systron-Donner analogue computer). > My only output devices are currently a pair of large, ex-Soviet, centre-zero > microammeters wired as voltmeters (ie: pure analogue.)

Surplus is your friend. I bought a raft of banana jacks in assorted colours from a surplus vendor a while back. They're great for prototyping. And you're right about needing a lot of them, I looked at some of the analogue computers available on eBay, and the panels are just covered with them. - John -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
