The favoured modem of the early British hacker, the WS2000 was an approved modem from the early 1980s that packed just about every contemporary standard into one box. It was nevertheless quite a simple design, based on the AM7910 World Chip single chip modem from AMD (yes, that AMD), but was clever in the way it allowed the host computer to control the modem's functions, including autodial and answer, by pulsing various control lines.
Although UK telecom approval forbade the use of the Bell American modem standards, the WS 2000 had them — and got away with it by having an end-stop on the rotary switch that prevented their selection. It was the work of a moment to remove that stop.
