You have access to a number of additional tests in the boot PROM called FORTH
Diagnostics. To invoke these tests, you must enter the FORTH Monitor.
Caution –
To run the FORTH Diagnostics, you must halt the system in an orderly
manner. When the operating system or any other standalone program has already
booted, do not press Stop-a to halt the system. Abruptly aborting program execution
may cause damage to data files.

Consult your software documentation for instructions on ending a work session and
