DTSS

operating system The first commercial time-sharing system,

created by Dartmouth College and sold by General Electric

around 1967.

GE's Information Service Divsion (ISD) marketed DTSS which was

running on a system called GE-265 (a combination of the

front-end processor the Datanet-30 and the GE-235).

DTSS was ported (and significantly improved by GE ISD around

1965-1966 on a combination of DN-30 and GE-635). This

proprietary system, called Mk-II, later improved by GE and

renamed Mk-III, is still working today (1997) as part of the

GE service bureau that also includes IBM and Unix

computers.
