Heathkit Continuing Education series

[Kenneth G. Gordon]

I checked what I have, and I have the following:

DC Electronics
AC Electronics
Electronic Circuits
Semiconductor Devices
Digital Techniques, Vol 1 and Vol 2
Microprocessors, Vol 1 and Vol 2

Total: 8

I have three of the earlier blue "trainers".

1) ET-3100 "electronic design experimenter"

This has:

 + and - 0 - 15 VDC variable regulated power supplies

30 VAC center-tapped "Line Frequency" source

A sine/square wave generator covering the range 200 Hz to 10Khz 
in two ranges.

A 1 K and a 10 K pot

and various "terminal boards" which use solid wire to jumper it all 
together.

I use this one for analog circuit design.

2) ET-3200 digital design experienter.

This has:

+ and - 12 VDC and + 5 VDC fixed power supplies

4 ea logic indicators

A three-frequency clock output, 1 Hz, 1 Khz and 100 Khz

Two logic switches

Four data switches

A square-wave Line Source

Various plug-boards.

3)  ET-3400 Microprocessor training system.

This includes:

A Motorola MC6800P CPU

4 banks of RAM

Control buffers

Data I/O

ROM

Key buffer

Address buffer

6 ea 7 segment LED readouts

A 17-key keypad 

+ and - 12 VDC and + 5 VDC fixed voltage power supplies

An 8 position dip switch for inputing binary data, with 8 ea LEDs to 
show their state.

4) I also have a later brown Laboratory Breadboard model ET-
3300B

This has + and - 12 VDC at 100 mA power supplies, a 5 VDC at 1.5 
AMP power supply and a bunch of the terminal strips.

All of these devices have built-in AC supplies, and are usually 
available on Ebay for reasonable prices.

I find them all to be quite useful.

I hope this information helps whomever was looking for it.
