1979: My first true home computer, an Intersystems DPS-1 S-100 mainframe with a 1 MHz (!!) 8080 CPU, 32K RAM, a pair of DS/DD 8" diskette drives, and several I/O ports. The large-screen display worked well with WordStar, and the Diablo daisy-wheel printer gave me letter-quality output. The lashup atop the DPS-1 was a stepper motor driven through TO-3 switching transistors from a parallel port on the computer.
