Did you see my blog on The Magic of Mock Relays in which I picked up a really tasty antique relay from my local electronics store?
After I found that antique relay, I became enthused with the idea of creating either a simple relay-based computer – or maybe just a piece of "relay-art" in the form of a bunch of relays clicking away doing something in a glass-fronted wooden display case on my wall.
But they are sooooo expensive. The one I picked up cost me only $5, but equivalent models cost anywhere from $25 (on eBay) to $100 (from special stores that supply the government with obsolescent parts).
