So I was at a yardsale today and bought a Heathkit CO-1015 oscilloscope. Neat. I also found some user manuals on ebay but it doesn't have the cord/sensor on it. I couldn't find one of those on ebay.
Anyone know anything about them? Are there grassroots plans for using a coat hanger or small raccoon wrapped in tinfoil to get it to work?
At any rate, it was 50 cents. I also got a vintage A/C vacuum pump that works like a charm for $5
