We are having an oscilloscope party!
Have you heard about an oscilloscope built like a Douglas DC3
If you read electronics magazines some 20 years ago you know what I
mean. Gould had full page adverts about their OS300 oscilloscope with
a DC3 beside it.
The idea was to illustrate something built to last for a long time.
Gould sold a batch of half built scopes to a medical lab.
These scopes had no front panel, no attenuators, no time base switch,
etc.. They were going to build their own special plug-ins.
The project was abandoned and these scopes came out on the surplus
market. I knew a guy who had bought one of them extra cheaply because
it was faulty. He couldn't fix it so he sold it to me for 100 dollars.
I found a faulty transistor and replaced it, and then I built the
front panel with all the switches and other stuff.
I still use it and like it. It is simple and reliable, and the
frequency response is 20-30 MHz.

*Much as we admire the Dakota's traditional hard-working virtues,
sadly its last spec update was in 1945. The Gould OS300, on the other
hand, offers 1980's features - dual trace with true 20 MHz operation,
continously variable amplifier sensitivity to eliminate loss of
bandwidth over the 2 mV to 5V/cm, X-Y-operation, P43 phosphor and
quick heat cathode for rapid set-up and brighter displays.
