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
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.
