One of my favorite early personal computers! I regret that the designer
didn't give it a name, though. Specs:

Name: "Electronic Computer"
Intro: Jan 1960
Price: approx $35
Technology: discrete transistors
Memory: 6 bits
Input: rotary telephone dial
Clock speed: as fast as you can dial
Output: 12 incandescent lights
Programming language: patch cords

The author describes how to add, subtract, multiply, and divide on this
box, but it's really more of a calculator than a computer since it doesn't
have control logic or a clock.

I hope to do a web page some day that describes this machine and several
other home computers from the 1950's and 1960's.
