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. Cheers John

New Find! Rolm 1602... Does anyone have any info/pointers/etc...?

by CordaAJ＠nswc.navy.mil

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... -al- -acorda(a)geocities.com

Defining Disk Image Dump Standard (ACHTUNG very long!)

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. > - I would even go further and > restrict all markup specific parts for only using the characters > A-Z, 0-9 and some well defined (read only the absolute necersary > minimum) characters.

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? -doug q

Info on the Dynalogic Hyperion

by mgregory＠vantageresearch.com

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

Nixdorf LK-3000

by doug＠blinkenlights.com

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

Racal/Blackbox BTS-100 term. server

by rdd＠smart.net

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. -- R. D. Davis rdd(a)perqlogic.com http://www.perqlogic.com/rdd 410-744-4900

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..
