Heathkit ET-3200

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.

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 http://www.davididay.com/Gnome/products.htm ).
