IIRC you go to
http://www,vt100.net/rm/ and follow the
obvious link for
documentation. Near (at?) the top of the list is a
source listing for
an
early version of the COS monitor. It's about half a
megabyte, pdf.
My mistake is assuming I was the source for the manuals there -
obviously some others snuck in that's one of them!
But I'm sure I've seen a listing in paper form, so I still need
to go hunting in the attic.
