[edit] Summary

Radio-Electronics, July 1974, Volume 45, Number 7

Gernsback Publications, Inc. Publisher: M. Harvey Gernsback, Editor: Larry Steckler, Cover Photo by Walter Herstatt

Build the Mark 8 Minicomputer, by Jon Titus. "Your personal home-built computer. Use an ASCII keyboard or tie in a TV Typewriter. Complete with expandable semiconductor memory."

The article (on pages 29-33) gives a description of the features and circuit. Readers could order a 52 page booklet for $5.50 that showed complete schematics and printed circuit board layouts. Radio Electronics sold thousands of booklets.

A complete set of circuit boards could be purchased from Techniques Inc of Englewood NJ for $47.50. The set included these boards, CPU, Address Latch, Input Multiplexer, 1K Memory, LED Register Display, and Output Ports. A complete kit of parts was not offered. The 8008 microprocessor IC was available from Intel for $120.

Hugo Gernsback started Radio Craft in 1929. The magazine became Radio-Electronics in 1948 and then Electronics Now in 1992. It was published until December 1999 when it merged with Popular Electronics to become Poptronics.

This 8.25 by 10.75 inch (21 by 27 cm) magazine has 100 pages. The monthly paid circulation was about 160,000.

[edit] Fair Use in Mark-8

• This was the first microprocessor based computer kit to be published by a major magazine. Radio Electronics' publishing of this Mark-8 computer and the TV Typewriter in September 1973, forced Popular Electronics to respond with the Altair 8800 in January 1975. The personal computer revolution was underway.

• Jonathan Titus's original Mark-8 is at the Smithsonian Institution in Washington, D.C
