I haven't used a 320 for a _long_ time, but lemme see how much I can 
remember.  On the CPU board (the one containing the serial port), there 
should be a set of DIP switches.  *One* of them should be clearly marked 
"remote".  To use the internal serial port as console, set that switch to 
"1".

Hmm ... I don't have the pin-outs handy.  I have the snazzy HP adapter 
db9->db25 adaptron on mine.  I'll see what I can come up with.  If anyone 
else has that info, that'd be great.

I'm using a serial console on a 340.  I have used a serial console on a 
320 before.

There are a couple of ways to figure out the CPU model.  Look on the CPU 
board.  If it has a 68020, it's one of {318,319,320,330,350}.  If there is a 
68020, look for a 68851.  If a 68851 is present, it is one of 
{318,319,330}.  The NetBSD kernel treats the 318, 319, and 330 as one CPU 
type, and the 320 and 350 as one CPU type (the 320 and 350 have an HP 
MMU/VAC).

I have a 319.  It's in a thin, long case.  I've never actually seen a 318 
or 330, so I can't speak for them, though I'm guessing that a 330 is the 
68020/68851 on a DIO card that plugs into a regular DIO-II backplane.

The 320 has no DIO-II, and the memory is on little boards that plug into 
the DIO backplane.

Hope this helps a bit.
