Like the Heathkit ET-3100, the Heathkit ET-3200 is a fairly simple device containing some power and signal generation circuitry along with a breadboard for creating electronics experiments using those features.
Where the ET-3100 is designed mainly for basic electronic experiments using analog circuitry, the ET-3200 is more geared towards digital experiments using digital circuitry.
The device in my collection was donated by Mary-Anne Boulet.

I actually built one of these and used it for
years. The basic problem that Heath-Kit had with
this and other breadboard models is that they
were very delicate. I was always breaking off the
proto blocks for the various inputs and outputs.
I actually built some of my early Z80 and 8085
stuff on this bread board.
When I was in technical school from 1971 to 1973
I built an earlier version of this. I started
with a blond oak Victorian letter box. I had
eight input rockers and eight LEDs to monitor
signals. I also had a clock and two push button
switches. I replaced the original hinges on the
letter box, added a single brass trunk latch and
a handle.
I just completed a design of a new breadboard for
the PIV16F877 processor. It connects to a host PC
via USB2. I brought out all signals to the front
panel where I added a small bread board (see
