UNIX has the routines mapalloc() and mapfree() which manage the map -- this mapping is for NPR I/O only, and operates independently of the Kernel/User address maps.

Ie: UNIX can pretend that the machine is an 11/70 -- except that some of the registers are at different places, and a few extra lines of assembler are needed in the machine assist startoff section. Really most convienient. -M
