Re: [neonixie-l] 2 Hickok Ford Vehicle Simulator Analog computers
Way back in '69 I used boot eyelets soldered into PCBs for the 4mm sockets. Didn't get a cheap solution to the plugs though. None of the bent metal, springy-wire ideas survived use. One idea that nearly worked was a smaller eyelet for the socket and very flexible meter lead cable for the leads/ plugs. Stripped the cable, bent the strands back over the insulation and held with heatshrink. Later [ late '80s] I used wire-wrap pins and the rolls of "blue links" - can't remember the brand etc. The ones that I still have are on blank generic spools. They are continuous wire with a socket to suit wire-wrap pins every 6 inches. Worked but didn't look nice; very cheap though. A mate's contender at the time used an idea that I discarded - high density plug pins that had an insulation displacement connection slot at the end. he soldered the pin end into the pcb and pushed the 'telephone' wire into the knives to make the connections. Wasn't nice to use [for me anyway] and 'pulling' a connection wasn't easy [ needed plier on the short side and pull both sides together. The temptation was to just rip the wires out.] Found a rolled up piece of mylar recently - was the artwork for one of the patch panels - double-size done with Bishop Graphics tape. The high temps in that area had helped the tape fall off :-(( John K Australia clip . My biggest part of the design challenge is getting the cost of the patching down - even cheap banana jacks become expensive when you need hundreds!

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.

They could be jumpered into any part of the simulation circuitry. As I understand it, they were used primarily to set up the initial parameters more precisely than the verniers could.

Quoth lai...@wcoil.com at 2014-02-04 00:09 ... Check out auction 350987319019. It appears to be partial analog computers made by Hickok that simulate Ford vehicles. Most likely solid state but check out the card readers. They look like cardmatic tube tester card readers. So maybe you could simulate the suspension on a Pinto and test a 6L6 on the same machine! Standard disclaimer, not my auction etc. Tim Laing Oh, my. If I had the space and a squillion dollars for international shipping, I'd take 'em like a shot. John - any idea of what the Nixies in the Sequoyah were for? Voltmeters? Of particular interest, as I'm in the throes of designing a simple analogue computer. My only output devices are currently a pair of large, ex-Soviet, centre-zero microammeters wired as voltmeters (ie: pure analogue.) Had been wondering whether to include a digital voltmeters too.
