The Multics Input/Output system

R. J. Feiertag, E. I. Organick
1971 Proceedings of the third symposium on Operating systems principles - SOSP '71  
An I/0 system has been implemented in the Multics system that facilitates dynamic switching of I/0 devices.  ...  of all features of an I/O device but require considerable knowledge of the I/0 System and the device.  ...  By contrast the role played by the input/output control system in a Multics system is decidedly secondary, at least from a conceptual point of view.  ...

Protection and control of information sharing in multics

Jerome H. Saltzer
1973 Proceedings of the fourth symposium on Operating system principles - SOSP '73  
The design of mechanisms to control the sharing of information in the Multics system is described. Five design principles help provide insight into the tradeoffs among different possible designs.  ...  The paper ends with a discussion of several known weaknesses in the current protection mechanism design.  ...  The final step of "locking up" the supervisor lies in management of source and sink input-output operations.  ...
