DOS man sues over book allegations

THE MAN credited for the big idea that built MS DOS has sued an author who claims the sofware ripped off Gary Kildall's CP/M operating system.

Tim Paterson has started a defamation case against Harold Evans and the publishers of his book entitled "They Made America."

Paterson developed his software in the late 1970s while working for Seattle Computer Products. Vole bought the technology in the early '80s and used it as the basis for its own MS-DOS.

However "They Made America" which is all about Evans, the founder of Digital Research, alleged Paterson's operating system is dubbed a "slapdash clone" and "rip-off" of Kildall's developed in the 1970s.

Evans said that the intent of his writing was to "correct history" on what role Kildall played as a software pioneer. He said he had a vigorous defense against Paterson's suit. You can read more of this stuff ici la.
