Well of course you wouldn't see the Commodore Hyperion listed in the SWoC!
the SWoC page deals only with 8-bits (the C= 900 being the only exeption) &
intentionally excludes any C= PC clones (Which the C= Hyperion *might* be).
Anyway, I saw that computer listed the Canonical List of Commodore Products,
so it must exist. Besides, all I know is that it *looks* like the Dynalogic
Hyperion, I was only theorizing that it *could be* the same thing. As soon
as I find a site/picture of it, then I can figure out if it truly is a
Dynalogic Hyperion with a Commodore nameplate on it.

It would be interesting to know, precisely, what it is you intend to do.
There's nothing difficult about any of the telco stuff, but unless you have
a clear and well defined, as well as well-specified, goal in mind, you'll
never get there. Now, if you just want to blink some LED's I'm sure you
can do that.
If you want to interrupt your LINUX box each time the phone rings, you can
do that in a number of ways. If you want to make a phone ring, that's easy
too.
I've looked through a lot of discussion about this subject, but still have
no idea in the world what exactly, it is you'd like to accomplish. Have
you?

Gee, that's too bad . . . I don't spend money on "the industry" so I don't
follow the high-tech stocks. Maybe it didn't work so well over the long
run.
By the time they started making disk drives, it was so costly and difficult
to build anything but an exact copy of IBM's circuitry for attaching a hard
disk to a PC, which was by then the only mass market remaining fairly
healthy, they probably felt they had little choice but to use their own
devices rather than eat them. This probably alienated their customer base,
but, since it was going away anyway . . .

I don't know this for certain, but I was once persuaded that IBM had held
the patent on 2,7 RLL and let it expire in '83. There were, of course, lots
of other run-length-limited codes which would also have worked, but the 2,7
was so well documented and worked so well, that everyone jumped on the
bandwagon once it became available. Of course, WD came out with a chipset
that supported RLL almost right away, too.
They lost a lot of customers when they started making disk drives, though
they're a major player in that realm now. I guess it worked out OK for them
(WD).

I recently aquired a Data General MV/4000DC minicomputer with three 200
terminals and one 215 terminal, a 6311 tape unit and a Comswitch II access
controller. I have rebuilt the tape drive and it works great now. I can
boot from the onboard hard disk and navigate the system. I have gotten
all 16 virtual consoles functioning.
I have very little docs on this machine so pretty much have to 'hack' out
anything I want to do which is slow progress.
Does anyone have documentation on this machine or the AOS/VS operating
system?
Does anyone have SYSTEM Media for this machine?
Does anyone have SOFTWARE for the machine?
If I can help YOU with your classic computer questions, please let me
know. I can help with:
Atari 8 bits - know and have lots. Lots of software too. (450+ disks) I
can help in:
Networking
Hard disks
programming in Basic
Various other languages
All variants of AtariDos (MyDos, SmartDOs, etc)
All Variants of Spartados including SDX
Atari ST series computers - have two and am running MINT.
Can help in TOS and a BSD unix clone I am running called MiNT which
stands for Mint is Not Tos.
CP/M 2.2 machines (z80 processor) such as ATR8000, ATR8500, Cromemco,
Osborne, Kaypro, etc.
I am a technician servicing Intel-based PC's so if you need support there
I can help in:
CP/M
all versions of MS/PC dos etc, Concurrent DOS too
OS/2
Windows x
Windows NT
SUSE and REDHAT Linux
SCO Openserver V
Windows NT terminal Server
GEOS
Sun Solaris (X86)
OS/2 Warp and Warp Servers
Novell Netware 2 thru 4
Lantastic
Novell Netware lite 1.1
General networking questions for above operating systems and hardware.
Please help with my MV4000DC. If you would like to see it you can TELNET
into my PC which is running as a terminal on the MV4000 and you can play
with the minicomputer that way! Just e-mail me and we will set up a time.
Thanks in advance,

I just did that accidentally to a Mac SE. :-( I was trying to remove a
cable from the innards and my hand slipped and wacked the board on the
back of the CRT and skewed it far enough to bust that little tit. Now I
have *more* spare Mac parts.

Okay, so now I have to go into the basement, and re-read the serial
plate. NCR's numbering scheme is *not* intuitive.

I think that mostly applies to the '020 machines and higher. When I
first got my machine, I was told that it didn't really support
TCP/IP.

I'm pretty sure that's the case. The 68010 was kinda like the
80286-- some memory management was there, but it was considered
kinda brain-dead. The 68020 was the real breakthrough. Operating
systems for the 680x0 really took off after that.

That's about right. I have a complete set of spares in my closet.
The system board is *huge*.

Now you've got me worried. I really ought to take time to fire
up the thing.

Well, I merely wanted to state that while NCR 'rolled their own',
it really wasn't anything special. The wd-100x chipset certainly
was revolutionary, however. That meant almost anyone with a wire-wrap
tool and enough parts could interface a winchester to just about
anything (like say, a Xerox machine?). That was a major breakthrough
in 1981, but by 1984 (when my machine was built), it was pretty standard.
Who held the patent on RLL, and (consequently) lost their shirt
when it became standard on 'smart' disk drives?

No, I don't mean the ComTerm Hyperion. When I said Commodore Hyperion, I'm
not bullsh!tting, I actually mean Commodore Hyperion. All I know is that it
looks like the Dynalogic Hyperion.
By the way, ComTerm didn't make the Hyperion, a company called Dynalogic
did. It sold relatively well (well, considering the state of the IBM clone
market in early 1983). Not too long after they released the Hyperion, they
were bought out by a company called Bytec, & they sold the Hyperion under
the Bytec name. Later still, Compaq released the famous Compaq Portable, &
we all know what happened from there (wither Bytec/Dynalogic).
