The boot ROM in a Series 200 (and series 300) has a very extensible set
of drivers for reading from disk, writing to terminals, and reading from
keyboards, until a "real" operating system (with drivers) is loaded.  
The ROM "steals" some low RAM (160 bytes, as a matter of fact)
for storage of tables and vectors.  Any operating system should preserve
this space.  From the amount stolen I would guess that you have a 3.0 boot ROM.
This is documented in the Pascal Workstation System Designer's Guide.

This should probably be amended to indicate that HP's enhanced version,
called HP-UX, does not run on the 9816.

Correct, with a plethora of capacities.
