The Heathkit ET-3100 is a fairly simple device containing some power and signal generation circuitry along with a breadboard for creating electronics experiments using those features.

The device in my collection was donated by Mary-Anne Boulet.

I've inherited an ET-3100 from an uncle of mine. It came with two workbooks, but no accessory wires for projects. It's in mint condition - looks like new compared to the picture above. We are thinking of trying to sell it - what would a fair asking price be?

This was used with Heath's AC and DC courses. There isn't a lot of circuitry involved - a transformer, function generator and variable regulated supply. You could build one of these really cheap. Schematics are all over the web.

This is definitely not a computer or even something that does logic. It is more of a signal generator. I was going to say synthesizer but the lowest frequency is 200Hz--in the audio range, but not at all to the bottom of it. I think it could be used for computer clocking up to, well, As I look at it again, the top of the audio range, 20kHz.
