Editing PDP-10 (section)

== Clones ==
In 1971 to 1972, researchers at [[Xerox PARC]] were frustrated by top company management's refusal to let them buy a PDP-10. Xerox had just bought [[Scientific Data Systems]] (SDS) in 1969, and wanted PARC to use an SDS machine. Instead, a group led by [[Charles P. Thacker]] designed and constructed two PDP-10 clone systems named MAXC (pronounced as Max, in honour of [[Max Palevsky]], who had sold SDS to Xerox) for their own use. MAXC was also a [[backronym]] for Multiple Access Xerox Computer. MAXC ran a modified version of TENEX.<ref>{{cite interview |title=Oral History of Charles (Chuck) Thacker |interviewer-last=Kossow |interviewer-first=Al |last=Thacker |first=Charles |subject-link=Charles P.

Third-party attempts to sell PDP-10 clones were relatively unsuccessful; see [[Foonly]], [[Systems Concepts]], and [[XKL]].
