Hello all. At a recent VCF (the midwest one) I obtained 2 SparcStation
LXes and a HP 9000/300 (I'm more interested in the latter as I have
gotten the LXes to do functional things already). With the resources
online, I've still been unable to tell what kind of 300 series system
this machine is. It's case is about as tall as a sparcstation LX, but
wider and lengthier. It has nothing but a power switch and light on
the front panel. The main system board has a m68030 cpu, with an empty
plcc (i think) socket next to it. There is a bank of 8 dip switches on
the right side of the board (if facing the ports) near the HP-IB port.
The system board has the following connections, left to right.

RS-232 (DB25-f), VIDEO (single RCA-F jack), SPKR (single RCA-f  jack),
HP-HIL jack (Don't wory about that, I have crates of HP-HIL crap here,
in fact, I'll give some of it out for free on this list in the
future), HP-IB jack.

It has a network card and a second HP-IB card. I would like to get
this to netboot NETbsd, or better yet find some HP-IB disk systems
(anyone got em' ?) and let it boot HockeyPUX-- hell, or netboot
hockeypux. But therein lies the problem-- aside from the HP-HIL
keyboards from my dead 735s, and my AUI-TP ethernet tranciver, I've
got nothing else that will work with this. How do I hook up a monitor
to it. I hear that it can take a color display card that has RGB bnc
jacks on it. Does anyone here have such a card, and could I buy it
from you if you do, or is there another way to hook up a display I may
already have other than that? Can I get this thing to show any signs
of life other than a power light with something I have here? (like a
serial console).

Any help getting this thing to work would be greatly appreciated, as
I'd really like to get it working and add it to my collection of
obscure computers.

Now to the LXes:
I wired a plain 13w3 - R G B BNC adapter that works fine with my SGI,
but it wont work on either LX. The monitor goes on but doesnt show
anything (I know I'm booting without a keyboard, but I'm talking about
when I'm in open firmware via an RS-232 console and I switch the
output to the screen) What do I need to do to fix the adapter?

What version of solaris should I run, and where should I get it (One
is running linux now, the other has a wiped HDD)?

What kind of keyboard do I need for them, and where do I get that?


Any help, especially with the 9000/300, would be GREATLY appreciated,
and thanks in advance for [hopefully] the replies.
