I have been contacted by a person who was an Amiga developer and
who wishes a rather large stash of Amiga Stuff to disappear from his
garage, thus precluding the onset of domestic disharmony.
And, as conscientious collectors, it behooves us to maintain
harmonious domesticity, if in our power to do so...
Please contact Don Jenkins at wa6ogh(a)msn.com for more info.
I am posting this for Don, so please contact him directly.

Hi!
I just picked up a Rolm 1602 system at a local hamfest. It
looks like an interesting toy (and a way to expand my horizons
beyond the Sun/SGI/Dec arena. It even has a front panel
interface :-)
The unit seems to be in pretty decent shape (apparently it did not
go through "Military" (i.e. sledgehammer) decommissioning,
as the party I bought it from indicated that he obtained it from a
NASA surplus auction). Unfortunately, there were no docs
whatsoever with this critter. I seem to vaguely remember that
some of the Rolm systems were just repackaged and beefed-up
Data General Novas, but I could be wrong. Can anyone provide
me with info/pointers/tech docs on this critter? I've done a
web search and a dejanews search, but haven't had any luck.
I even checked through some of the classiccmp archives, since
I remembered seeing something on a Rolm system here a few
months back, but I was unable to locate anything.
Some of the things I'd like to know (or find pointers to):
Hardware interface pinouts/docs:
i.e. where do I connect an ASCII
terminal... (There is no obvious serial connector,
i.e. DB25, etc. All the connectors are some
sort of mil-std twist-lock jobs)
Does this critter have a disk interface of
some sort, etc.
Power requirements and pinouts:
The previous owner had an AC line cord
attached to a connector on the back,
but I don't necessarily trust that he knew what
he was doing. Is this really capable of running
at 117V@60Hz, or did it need something oddball
like 400Hz?
Instruction set documentation:
So I can play with the front panel :-)
Software:
i.e. Did this thing have a simple executive program of some
sort? I downloaded Bob Supnik's Nova emulator in the hope that
it might provide me with some hints as to Nova architecture,
but there wasn't much documentation there. Will a Rolm 1602 run
DG Nova code? If so, is there an archive of DG Nova
software somewhere?
The back of this critter uses a bunch of what looks like mil-std
twist-lock connectors. Does anyone know an (affordable)
source for these? I'm going to try pulling it apart tonight
(It appears to be held together by about 17,000 screws :-).
Any info would be greatly appreciated....
-Thanks in advance...

:-) I only included it because there appeared to some strong opposition to
"wasted" bytes. What I did was bolt tags onto the binary, deliberately
producing what Tony accurately described as the worst of both worlds.
Actually, if you look at the examples, the ASCII form in the tags, at
least, typically takes just about the same space as the binary would, so
there's absolutely no reason to use anything but ASCII.

Thereby avoiding 99.9% of the problems raised by incompatible character set
representations. Agreed.

That's only a thousand on a CD ;-)

Tom,
Browsed your information and thought maybe you could direct us to a parts
center for HX-20. In need of the optional mini cassette recorder.

Here's another one for those with long memories. Who remembers
subcode graphics? I have one audio CD that contains subcode
graphics that I've never been able to view (they're encoded in
something like the Euro Teletext format).
Anyone know how to read and display subcode graphics?

Hi Leo,
bad news, I'm afraid. When I went back to my local thrift shop on the
weekend, the Hyperion that had been there for a few weeks was gone. I asked
the clerk if she knew whether it had sold or been dumpstered, but she had
no clue. A quick check of the dumpster didn't turn up anything either : v
(
Still, I'll keep my eyes open. They do seem to turn up every now and again
around here. They must have been popular with the oilpatch guys, who were
on the road a lot.
Regards,
Mark Gregory
I'm trying to find some info about the LK-3000, an early hand-held
"computer". I think it was made by Nixdorf around 1979, but it was also
sold under other labels (I think I've got a "Lexicon" labeled instance
someplace).
Can anybody tell me what modules were available? Was there a module that
made the thing user programmable, for example?
Is anybody aware of a pre-1979 programable handheld? I suppose something
like the HP-65 is a candidate, but an alpha-numeric keyboard and display
would be more compelling.
Assuming the LK-3000 isn't user programmable, would anybody take offense
at somebody calling it the first PDA?
(No, I'm not selling one on eBay. There is one for sale there now -- it's
overpriced, though. These things aren't exactly rare.)
Thanks,
Doug
Greetings,
Would any list members happen to be familiar with a terminal
server sold by BlackBox that was oroginally manufactured by
Racal-Datacomm, model No. BTS-100?
A while back, I obtained one of these, but I can't seem to get it to
work by connecting a terminal to the console port; I've tried data
rates between 300 and 19,200, and nothing; also tried a few other
ports. Something tells me that the best thing to do is reset the
server to the default settings, but I'm not sure how to do this; no
reset switch inside, but there is is a jumper inside that I'm going to
try changing next. Any ideas for sources of documentation? The
manufacturer and black box consider it ancient and can't help.
Also, is anyone her familiar with the apparently not-so-rare defect in
Emulex Performance 4000 terminal servers that causes a short circuit?
I'm told by Emulex that they have an idea what the problem is, as a
certain something is known to go bad in these units, but they refuse
to tell me as I'm not an authorized repair center. Short of
unsoldering surface mount ICs, I've disconnected and removed
everything that I can find to disconnect and remove, and the short on
the circuit board remains. The PSU seems ok when I apply other loads
to it.

Don't forget the fact that LP's and 7 inches (45's) are still being pressed
today... I ought to know, since I buy some of em... I have about 80
something records of all types, and about 50-60 of them were pressed in the
last 5-7 years. Now if only they made blank recordable 8-tracks still, I
want to record some music from CD on 8 track so I can listen to it in my
car..
