Or the built-in monitor that you got when MacsBug
wasn't installed.

A MacsBug command I remember using a lot on my
Mac Plus went something like

   DM DFFFFF1F

I can't remember the exact number. My only record
of it was written on a box of stick-on labels that
I kept, long after it was empty, in a strategic place
on my desk. Recently I threw it out, only remembering
its significance afterward. Not that it really mattered,
since it didn't work on any model later than a Mac
Plus anyway.

Oh, what did it do? Another virtual chocolate fish
is on offer for answering that...
