Let’s see ... “CTSS” (Corbatò et al) stood for “Compatible Time Sharing
System”, the “Compatible” part meant that it could not interfere with
batch workloads run under the IBM-proprietary OS on the same hardware.

Later some hackers at MIT created their own OS for the PDP-10 and named it
“Incompatible Timesharing System” (ITS) as a sort of anti-homage to
CTSS. ;)

(You thought “MULTICS”/“UNICS” (later “UNIX”) was the only pun of its type
to come out of the ferment of OS development in the 1960s?)
