Here's an overview of the multi-user capabilities available in OS-9 Level II on the Color Computer 3, as well as OS-9's basic security mechanisms. I use my Apple IIe as a terminal to the CoCo 3 in order to better demonstrate how the system behaves in a multi-user setting.

To duplicate what's seen here, you'll need either NitrOS-9 or the original OS-9 Level II distribution from Tandy as well as the OS-9 Level II Development System, which includes login and tsmon.
