first to implement a time-sharing system, in a project led by Robert Fano and Fernando Corbató. A demonstration version of MIT’s CTSS—the Compatible Time-Sharing System—was shown in November 1961. This early, experimental system allowed just three users to share the computer, enabling them independently to edit and correct programs

chance to go back to simplicity and get it really right. The original Unix was a third system. Its grandfather was the small and simple Compatible Time-Sharing System (CTSS), either the first or second timesharing system ever deployed (depending on some definitional questions we are going to determinedly ignore). Its father was the

for the AI Lab’s Digital PDP-10 minicomputer. The software was called ITS, the Incompatible Time-Sharing System–a conscious dig at the earlier Compatible Time-Sharing System, CTSS, which had been used to develop Multics, the progenitor of Unix. Although there was no real plan to his work–“I was just going

of the Kahn-Cerf internetworking protocol, or something very much like it. It would be open in precisely the same way that Fernando Corbat6's Compatible Time-Sharing System (CTSS) had been: anyone could join, and everyone could participate. Indeed, monolithic central control of the Multinet would be impos- sible, if only because its

operating system incorporated the hacking ethic into its very design. Hackers had built it as a protest to Project MAC's original operating system, the Compatible Time Sharing System, CTSS, and named it accordingly. At the time, hackers felt the CTSS design too restrictive, limiting programmers' power to modify and improve the program's

So overdesigned and overbuilt and over everything. It was close to unusable. They still claim it's a monstrous success, but it just
