MMD stands for Mini-Micro Designer
The first true single-board computer (see the May 1976 issue of Radio-Electronics) called the dyna-micro was based on the Intel C8080A, and also used Intel's first EPROM, the C1702A. The dyna-micro was re-branded by E&L Instruments of Derby, CT in 1976 as the MMD-1 (Mini-Micro Designer 1) and was made famous as the example microcomputer in the very popular 8080 BugBook series of the time.
