Technical Design Labs (TDL) was an early producer of personal computers founded in 1976 by Carl Galletti and Roger Amidon. TDL was based in Princeton, New Jersey, USA in the 1970s and early 1980s.[2] [3] [4]
The company was later (1978) renamed Xitan, in honor of its primary product.[5] [6]
In 1979, Neil Colvin formed what was then called Phoenix Software Associates after his prior employer, Xitan, went out of business. Neil hired Dave Hirschman, a former Xitan employee.[7] [8] [9]
In 1979, Carl Galletti and Roger Amidon had started a new business called Computer Design Labs that acquired the rights to all TDL software.[10] [11]
