He helped make the home computer ubiquitous by introducing the fully assembled Tandy TRS-80, which was so novel at the time that it became a museum piece.
The New York Times reports that John Roach, Pioneer of the Personal Computer, Is Dead at 83. Roach was the executive who introduced the Tandy TRS-80 in the 1970s, one of the first fully assembled microcomputers. I didn’t realize how dominant the TRS-80 was in the late 1970s. At one point it held 40% of the market. We usually hear about Apple and IBM, but not about the TRS (Tandy Radio Schack).
They later released a laptop or tablet computer that I lusted after, the TRS80 Model 100. This was a keyboard and a small LCD screen and enough software to type notes or edit text. There was also a modem to send your writing somewhere. I still think this form factor makes sense. You can’t really type on an iPad (unless you get a keyboard for it) and you don’t really need lots of screen for typing notes.
