MCBs

Multics Checkout Bulletins Index

Multics Checkout Bulletins (MCBs) were development white papers produced by project members and circulated to the development team. Over 1076 were produced between 1967 and 1973 by MIT, Bell Labs, and GE/Honewyell staff. They were superseded in September 1973 by Multics Technical Bulletins.

Over 1000 MCBs were produced.

(July 2018) about 100 MCB citations were extracted from repository document B0099. We need many more.

According to Jerry Saltzer, the MIT Archives has the follwing:
box 91 MCBs 1-149, 1967-1968
box 92 MCBs 150-548, August 1968 - August 1970
box 93 MCBs 549-639, August-December 1970
A table of contents listing MCBs may have been published as an MCB.
