When you first power the box up, do you hear the disk spin up, reach
what sounds like operating speed, then after a few seconds, spin down,
then spin up, ditto, then spin down and stay down? If so or similar,
that is likely the dreaded RD53 spin-up-spin-down disease. There have
been a variety of suggestions as to why this happens - but given HDC
is not currently enabled, why not just consider it dead for now?
I don't off hand know whether you need it as a load - I do know expansion
boxes without a CPU board do need additional load on +5V to keep the
switching PS doing its thing. It may be the same for the +12V rail.

I don't see any question marks, so I believe the self-test passed.

| attached monitor/keyboard, or do I still need to build a "console" cable?
| (Or does this port not use the common DE-9 pinout at all?) I intend to

| same machine I'll use for disk service); any problems there?
I've not tried it but I vaguely thought Ragge had added console support
via the monitor/keyboard. I only use the DB-9 port with a glass tty.
The console (i.e. DB-9) is special. In order for the PROM to think
the otherwise printer port is instead the console, you need to have
a cable that shorts pin-8 and 9 I believe. It has been mentioned before
on the list - you may need to hunt back though via the vax-port mailing
list on www.netbsd.org.
I've used the DB-9 console cable that comes with uVAX-II's as my vs2000
console cable (it does the right pin shorting magic). I've used kermit
via a NetBSD/i386 box so I don't know why you can't use a 5000/25.
