Abstract: This general purpose program will handle the priority schedul-
ing of different I/O devices, with a minimum of disturbing time. It
provides: hardware and software interrupts, 12 levels of priority plus
background plus interrupt off, saving all active registers (including
arithmetic and memory extensions) plus one memory, loading in 3 pages
of core plus 16 memories page 0 in field 0, queuing low levels of priority,
masking interrupts if wanted, high speed servicing--and no bugs--
hopefully.

Note: Documentation and listing comments are in French.
