Mark-8

The Mark-8 is a microcomputer design from 1974, based on the Intel 8008 CPU (which was the world's first 8-bit microprocessor). The Mark-8 was designed by Jonathan Titus, a Virginia Tech graduate student in chemistry. After building the machine, Titus decided to share its design with the community and reached out to Radio-Electronics and Popular Electronics. He was turned down by Popular Electronics, but Radio-Electronics was interested and announced the Mark-8 as a 'loose kit' in the July 1974 issue of Radio-Electronics magazine.
