The
Breadboard Circuit Design Trainer ET-3100 came
on the market in 1976. There was also a pre-assembled version ETW-3100.
Several other Heathkit
products could be bought
pre-assembled and many of them, but not all, had the "W" in the type designation. The ET-3100
/ ETW-3100
was then replaced by the ET-3600
/ ETW-3600
in the early 90's. The ET-3100
was a product designed for educational purposes and that was what the Heathkit Educational Systems (HES) was fouded to do. Heathkit Educational Systems of
today is still making this kind of products. The today's counterpart to
ET-3100
is the ETS-3600 (or EWS-3600 as pre-assembled). My ET-3100 (or rather ETW-3100) is an OEM version made for
Esselte and was used in
schools in Sweden. I remember using them my
self in school in the late 70's. The Original ET-3100
was in blue color but the
OEM versions came in several different colors.
   I have slightly modified my ET-3100 by having extended the breadboard and added 4mm test terminals to make it easy to connect a VTVM or an oscilloscope to the supply and the signal generator. |
