The Mark-8 was originally a do-it-yourself project published in the July 1974 issue of Radio-Electronics magazine. Its creator, Jonathan Titus, also sold kits. The Mark-8 created a great deal of excitement among electronic hobbyists because it was a fully functional computer that was inexpensive to build. Completed systems had a reputation for being very reliable, too. It’s not known how many of the 7,500 plans that Radio-Electronics sold resulted in completed Mark-8s. Titus sold about 400 kits.
