Applied Digital Data Systems
ADDS, or Applied Digital Data Systems was a leading supplier of high-quality video display computer terminals, founded by William J. Catacosinos[1] together with SSDS (Solid State Data Sciences) in 1970.
It became a subsidiary of NCR in 1980, which sold the Mentor 2000 professional computer in the United States in 1986.
The Mentor 2000 ran at 5 MHz using a Zilog processor, 640KB RAM, and included one 60MB hard disk. It used the Pick operating system and database management system. It was able to manage 16 or 32 video terminals at once.
ADDS (along with NCR) was later part of AT&T,[2] then independent briefly before being acquired by SunRiver Data Systems.
