20x1 pin edge connectors for Moog cards workaround: 22x2 pin

[Ricko]

I just thought I'd share this, in case anyone is in the same boat.

I bought some Polymoog Polycom cards (from Synthfool store, which is so great) a while ago, and since then I have been trying to find a source for the 20-pin (20x1) edge connector (sockets) that were not more expensive than the cards. (Synthfool has some kind of edge connector for sale, but the photo is unrecognizable and certainly not sockeys.)

It turns out that the vintage amusement game people use double-sided 44 pin (22x2) connectors (sockets), so I got some on ebay (http://stores.shop.ebay.com.au/Austin-Amusements__W0QQ_armrsZ1) which the cards fit in well, though the sockets have two extra pins.

There is plenty of wiggle room, so I don't think it is necessary to get some polarizing keys to make sure of good positioning. (The keys are about 40c each at Jammaboard.com I found.)

I think some other Moog products used the 20 pin finger connectors too. The Dubsounds website estimates 3800 polymoogs produced, with 72 polycom cards per system, that means that at least 273600 cards and presumably more chips were made, and would seem to be a good resource for making into interesting synth modules. So where are they all?
