I asked about the mass of the thing, just to dream about shipping it. 6 boxes, 250 kg's or so apiece (over a ton). It's a fairly large system, eh?

It does, assuming you use the right device name for the Ethernet.
There is a MOP demon for Linux that some NetBSD folks have used to boot a
2000 diskless; you could look into that for info about the boot protocol.

Hello to the list members. I've just joined you.
Based in Australia, I have
Altair 8800b (don't ask the price!)
Kaypro II (found today - $30)
Exidy Sorcerer x 2 ($25)
Ohio Scientific Challenger 1P board (free)
Dick Smith Wizzard (aka. CreatiVision) ($10)
Sinclair ZX80 ($1)
Sinclair ZX81 ($1)
Sinclair Spectrum (trade for a slide rule)
Atari 800 + 810 (well my Mum has it, but I'm working on that)
Although not a big collector of the older computers, I am in general an avid
collector of smaller computing devices such as slide rules and calculators.
I'd like to announce my web-sites on these subjects...
Museum of Soviet Calculators
http://www.comcen.com.au/~adavie/slide/calculator/soviet.html
Slide Rule Trading Post
http://www.comcen.com.au/~adavie/slide/
My intent in joining, however, is to share my resources (boxes of software
for Exidy Sorcerer - but I can't load any of it - no working drive!) and
perhaps utilise the brain pool of this list to help me get my Altair up and
running, and also enable my Kaypro II to boot to anything but <System?> I
also have manuals for about 10 different Kaypro packages - email me for
list.
In any case, I was pleased to accidentally stumble on this list, and
fervently hope it is still an active one. I do welcome private
communications, but would generally prefer discussion on the list for the
benefit of all.
Cheers

That's B ESA0 for the Ethernet. But if he can't type, he can't enter any of
those commands. I don't know what the various failure modes of an LK201
look like (none of mine have failed), so I can't say offhand what's wrong
with the keyboard. I would first try swapping it (since I have plenty of
them lying around) and, failing that, going for a serial console.
Also, the ? on 7 indicates some sort of problem with the disk controller.

VS2k, uV2k and MV-II and a bunch of others. However if you have the
manual....RTFM comes to mind. :)
The NI boot protocal for small vaxen is MOP, to explain that requires a
book...come to think of it you may have that in your book.

I never heard of 320 x 200 x 16 for the CGA - I seem to remember 160 x
200 x 16 - surely it would not have had the memory for the other?
The CGA never did 640 x 400 x 2 that I ever heard of - I assume that was
a typing error for 640 x 200 x 2.
The EGA did 640 x 200 x 16 on a CGA monitor, 640 x [was it 400 or was it
350] x [a number of colours dependent on the memory installed] on an EGA
monitor, and even did 640 x 350 x 3 (I think) on an MDA monitor.
I also once saw a demonstration on a CGA card that changed colours in
real time faster than the scan rate and so gave more colours than you'd
expect.
But I digress. What was the question again? :-)
