Yes, Glen, I know already. No offense, but I'm looking for
information, rather than opinion.
I'm looking for info on an RT-4620-27A5S dual-CPU tower. It appears
to be an EISA? RAID-equipped server. All I can find is some references
on the NetBSD list, with no details as to the hardware.
Is it really, finally, truly the mythical NT-only computer?

The whole mid 80s thing with workstations was a disaster in many respects
as everyone was trying to put more processor in a box and unix was the OS
of
choice as it was easily ported and offered most of the higher level OS
functions
that stuff like DOS was clueless about. The problem was unix was easily
ported
though it didn't make for portable apps, usually due to underlying
hardware or
even the basic processor. In that respect CP/M and DOS made it easier as
at least if it was CP/M-80 you knew your base cpu was 8080/z80 and if it
was
DOS you could bet on 808x. Unix back then meant MIPS, VAX, PDP-11,
SUN/sparc, 68000, Z8000, and a few dozen I likely missed.

Note the 8051 is 1981.
I started with that chip using freeware under CP/M-80 and still use most
of those
tools. When there was a requirement I'd use a commercial compiler from
Avocet
systems a relatively inexpesive package back then. The idea that PCs
were a
unversal platform and was foreign to me until the vary late 80s ('89!).
Even then
DOS was the default not winders, assuming it wasn't SCO unix or the like.
In the end a lot has been forgotten about the timeframe from 82 to about
88
where there was not just a little flux in the market and the PC was only
one
player.

Actually there was but the problem of incompatable media was crippling
unless
you had the majik 8"sssd box. The realy 80s was an explosive time for
CP/M-80 software if you could get it in a form you could use. There was
a
large amount stuff published, but typing in 8-10 pages of listing was
often
a good reason not to persue it. What was also a bonus was the amount of
cheapware (low cost), stuff that was good but, cheap to buy.

Actually back (pre 83ish) then MS was a language and development tool
house
and I'd say a fairly decent one at the time.

get rid of by the end of the month. Although I'm into the 2200, I'm
interested in just a few early models.

It's a shame that it has so much power, and yet is so poorly engineered,
but I don't' suppose that's the point here.

Wow, you're really down on these "leftists," aren't you. I'm certainly
glad I've never met one ;) They sound scary, especially if they're
that much like windows.

...which leads to new ideas, which lead, of course, to cheese.
In other words, you may want to be more clear about your logic here.
Even though I agree in principle with the above, it's very sensational,
and there's nothing to support it.

I really hope you're not trying to make this into a more political

I don't think so. The fact that the standard exists, and is
generally followed, doesn't prevent somebody from making a new
standard or an extension to the old one where necessary.

It would be great if it did work that way -- now who's being

You _can_ with XFree86, and friends. I certainly hope you don't think
that those are the only X servers available. Some servers (while being
very nice programs) don't have this feature.
For the sake of argument I'll assume that you know all of this already,
and point out that you could also use keys on the keyboard, if you so
desire. I have done it before while using a Macintosh one-button mouse.

What kind of accent does man have? I hope it's not southern.

It's amazing DEC went to such
bother calculating VUPs by running
a set of real benchmarks on a finely
tuned system and then reporting a
measure based on some weighted
sum when this procedure would have saved
**sooo** much effort:
According to this proc, the machines
I can reach right now report:
VAXstation 4000-90A: 26.0 bogoVUPs (should be 32+ VUPs)
VAX 4000-700A: 30.8 bogoVUPs (should be ~40 VUPs)
VAX 4000-705A: 34.4 bogoVUPs (should be ~45 VUPs)
Alpha 2100 4/200: 35.2 bogoVUPs
Takara (EV56@500MHz): 87.2 bogoVUPs

I might have been the one that posted it. I snagged it from google, so

There was a version of DEC OSF/1 which early on ran on some of the DEC
MIPS boxes, but Ultrix has only ever run on the Vax and MIPS, not Alpha.

It has been my mission for some time to bring a BBC Micro back from
England. I would need some way to adapt British plugs to US sockets
and convert the voltage, and I would also need a PAL monitor. (No, I
don't want black-and-white NTSC. Yes, I could bring a montior back from
England along with the computer. I'm not sure if I want to do that.)
Does anyone have experience with these things? I am hoping to save
money ($500 would be above the top of my price range) but I don't want
to fry anything either.
Oh yes, and if anyone has an extra Beeb hanging around that would be
nice too.

They don't. The frequency won't matter, only having "about" the right
voltage. Actually, I once (when I worked for an Acorn distributor) came
across a guy working abroad who had inadvertantly used his unmodified Beeb
on a 120V supply and never noticed until he bought a monitor -- which
refused to work at such a low voltage. I wouldn't suggest you try it,
though; it should be easy to change the PSU setting.
Many monitors may not care too much about the frequency either, but it's
probably easier to get one that can be set to 110V; a CGA or Amiga monitor
should work. I'd strongly suggest an RGB (TTL level) monitor rather than a
PAL or other composite colour monitor, as the higher-res screen modes
aren't too sharp when the colour signal is added to a composite signal.

Don't try it. Neither the adapter nor the Beeb's switch-mode PSU will like
it.
