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.
