_{Cover of the April 1980 issue of 80 Microcomputing}

80 Microcomputing was a magazine that was dedicated to the TRS-80 line of computers. The Model I was released in 1977. The Model II really doesn't belong to this series as it was largely incompatible and more of a professional workstation, the Model III was released in 1980 and the Model 4 was released in 1983. I never owned one but in my freshman year of high school, we used Mode IIIs and Model 4s in a BASIC programming class. The April 1984 issue includes:
