mon -- enter the Monitor

syntax:  mon

ex:      mon

Dumps you into your Apple's monitor.  Ctrl-Y or RESET or
3D0G will get you back to Davex.  (On an Apple IIgs, Q will
do it, too.)

(If the only kind of "monitor" you care about is the one
you're looking at right now, this command isn't for
you--it's for people addicted to machine language.)
