Re: Homebrew Analogue Computer
I'd be interested in seeing that circuit.
There are some photos of my EAI1000 in my flickr account (tony_duell). I have 3 analogue 'bays' in mine, each bay has 6 summing amplifiers, 4 integrators, 2 multipliers, 2 'free' pots (all 3 connections brought out to sockets on the panel) and 10 grounded pots (one end of the track connected to analogue ground, the other end and the wiper on sockets). There are also some digital functions, a couple of comparators, a couple of Dtypes, etc.
Fortunately I got a lot of patch leads with it. You can still get suitable leads (e.g. at RS) but they are several pounds each...
I've made one modification to it. I added a DB25 socket on the back (I made a new blanking plate, there's no permanent changes) wired to the edge connector on the control module. This brings out the 'external trunk' lines, etc. I've made a box of 4mm sockets that connects there so I can easily plug in a 'scope, XY recorder, meters, etc
