Multics was self hosting, able to compile itself on Multics using bootstrapped compilers, by the end of 1968. All Multics development, by Project MAC and GE users, moved from CTSS to Multics during 1969. Non-developer users began using Multics on a regular basis in July 1969, and MIT's Information Processing Center began providing Multics as a service in October 1969. EPL was replaced by a native compiler, Multics version 1 PL/I, in late 1969.
