Wang Laboratories, which already has a VLSI implementation of the basic 2200 16-bit processor, has kept faith with the 70,000 users of its aged 2200 family around the world by introducing a new line of 2200-compatible machines, the CS series. Details are sketchy, but the entry model in the CS line costs just $4,950 and can grow to a system supporting 16 users, and the CS models are pitched at prices 25% lower than those of the machines they replace. The 2200 series was Wang’s mainstream product until the incompatible VS series was introduced in 1978, and was a business and scientific mini packaged as a desk-top computer.
