Does anybody know how the 68k talks to the z80 on a 16B (and vice
versa)?  All I've been able to figure out to date is a pair of
apparently magic addresses ($7800d0 and $7800d1) in the 68k's memory
space; I'm still slogging through the XENIX kernel code for any
additional clues.  Any hints would be most appreciated.

Also, any info (or pointers to info) on Xenix's a.out format would be
appreciated too.
