I have a Heathkit EC-1 Educational Analog Computer with original manual I'd like to sell. The computer is in unknown functional condition (I don't know if it works right or not) but it looks pretty good. I'd guess I'd have to sell it as unworking. All the parts are there but some of the knobs are "stiff". This EC-1 was in storage since the 1970's ...... it was with some electronic test equipment I purchased at a surplus sale at a college. If you have an idea of it's worth .... either to a collector or as a parts unit please email me at badger(a)vbe.com Thanks, Mike Melland, W9WIS (Oshkosh,WI)
