Yeah, that's what I thought - if, of course, it's a bootrom version
that knows about netbooting.

Fairly sure.  I wasn't 100% confident, so I took a known-working NeXT
Slab (which has both 10baseT and 10base2) and moved the tee connector
from the hp300 to the NeXT; it booted fine.

Based on what just happened with my 425e (see below), I think it really
was the ROM revision.  (Also, when using the 320, which had AUI
Ethernet, I used a transceiver which had separate send and receive
activity lights; the send light never blinked.)

Join the club. :-)

My box of "HP300 cables" included three (I think, maybe only two)
cables with RCA plugs on one end and BNC on the other, obviously
commercially made (molded-on strain reliefs).  Presumably they were
intended for video between a 98544B and a 98786A or equivalent.

Definitely not what I've got. :-)

98774A, and experiment indicates it handles the video from a 425e,
which the 98786A doesn't.  (I have a cable with a HD-15 on one end and
a BNC on the other, which I believe I made from a BNC-to-BNC cable I
had lying around and a HD-15 connector.)

No, no, there are six green-and-violet boards, and then that
red-and-black board in addition.  The sticker on it calls it a 98620B,
and past messages on the list imply say the 98620B is DMA support.

The 330s already have one spare slot; they're 4-slot cages, with only
three occupied (CPU, human interface, video).

Well, I have two working HP-IB drives at present, a 7937 and a 7958.  I
have a second 7958 that seems to have decided to die.  (Are the drives
in those things compatible with anything else in the known universe?
Standard ESDI, for example, or anything like that?)

The 7937 (furrfu, that drive weighs roughly as much as I do!) has a
working 1.2 install on it.  I'm trying to build a 1.4T kernel there,
but it's dog-slow, and 1.2 to 1.4T is a big enough jump that I'm having
tools-to-build-the-tools trouble.  (I tried the kernel off the 1.4.2
CD; it fell over with an unexpected-trap failure before it even cleared
the screen and printed the copyright notice.)

Where does it appear?  Serial port 1?  Does it use peecee-"standard"
pinout for the serial ports?

I set it up on the house LAN and didn't start rbootd, but did start
tcpdump.  tcpdump saw the query packet Just Fine.  So I fixed rbootd
(as it stands in the version I've got, it hardwires /usr/mdec/rbootd as
the place the bootfiles live; I added an option to change that) and ran
it, and then it appears to load SYS_INST happily, the screen blanks,
and I haven't yet gotten the serial console stuff working enough to
tell what happens next.

I wish. :-(  I don't even see anywhere it *could* have HP-IB.

:-)  First I have to make it boot at all.  I'll play with serial
connectors a bit more...I have half a dozen DB9-to-DB25 things, all but
one of which are ones I made and promptly forgot the details of and
probably have one-off pin wiring.  I'll play with it....
