Hmm, older hp300s has a switch to set the console to the serial port  
( they called that 'remote mode' for some reason ) - no idea if the  
newer ones switch automatically if there's no keyboard attached. It  
might be worth the trouble to look at the mainboard, maybe there's a  
switch or a jumper to set the default, otherwise you'll need a HIL  
keyboard and either use the config menu or hold down the R key during  
power up.
Depending which graphics board you have the RGB cable is probably  
trivial - if it has only 3 BNC connectors that's red, green and blue  
with sync on green, you can feed that directly to any halfway modern  
monitor that understands sync on green.
Also, the 400s have two firmware images, one for DomainOS, one for HP/ 
UX, for NetBSD you need to set it to HP/UX mode. If I remember  
correctly they have a switch on the back for that. What I wrote above  
probably applies to HP/UX mode only.

have fun
Michael
