Allen-Babcock Computing

"Allen-Babcock Computing was founded in Los Angeles in 1964. The company was established by James Babcock and Michael Jane Allen Babcock to take advantage of the fast-growing market for computer time-sharing services." (Lehman 2008)

In 1966 the company developed "RUSH" [Remote Users of Shared Hardware], an interactive dialect of PL/I. (Rosin 1969) Between 1965 and 1966 they developed CPS [Conversational Programming System], a timesharing system that ran under OS/360, under contract to IBM. (Rochester 1966)

"In 1969 Allen-Babcock held a 3 percent share of the time-sharing services market along with other companies such as Call-A-Computer, Com-Share, Tym Share, and Adams Associates." (Lehman 2008)

In 1975 Allen-Babcock was acquired by Tymshare. (Hardy 2004)
