Zenith Z-90 startup

Any Zenith Z-90 owners out there (which appears to be the same thing as a
Z-89 / Heath H89, but with a DD soft-sectored disk controller)?
I was given one up a couple of days ago which isn't giving the expected
"H:" prompt at power-on - but it *does* give a blinking cursor, and hitting
off-line lets me type, and characters get echoed to the screen.
Right-shift-reset clears the screen and gets me back to the cursor.
Before I dig deeper, I'd like to verify that this isn't a feature, i.e.
that it's not auto-magically dropping into "terminal mode" at startup :-)
Unfortunately while I have masses of documentation for the machine, I'm
lacking a basic user guide which might shed light on any such mode; some of
the more detailed documentation that I have talks about rerouting the port
cabling to use the system purely as a terminal, but doesn't mention doing
any other configuration.
