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..

Available FT: DEC PDP boards

by mrbill＠mrbill.net

(I first posted this a while back, and was talking with someone about a trade, but I havent heard from him in almost two weeks now... Dave,if you're still interested, please get in touch with me ASAP) I've got the following assortment of PDP-11 boards and CPUs that have been sitting around for a few months; I'd like to see them go to a good home. Trades preferred; I'm looking for a small VAX to play with VMS on (MicroVAX 3100 or so), or other DEC parts (TKZ30, RRD42 cdrom drive, any VT3xx/VT4xx terminals...). Will consider any offers; I hate to have these lying around unused. Marked on handle: Other markings/desc: ----------------------------------------------- M7270 KD11-H LSI-11 CPU 18-bit M7270 KD11-H LSI-11 CPU 18-bit M7270 KD11-H LSI-11 CPU 18-bit M8186 KDF11-AA 11/23 single board with MMU M8186 KDF11-AA 11/23 single board with MMU M9400-YE REV11-C 240ohm terminator, cable connector M9401 (connected to M9400 with ribbon cable) M8013 RLV11 RL01 disk drive controller (1 of 2) M8014 RLV11 RL01 disk drive controller (2 of 2) I've got some other cards as well, but this is all I can find for now. If anybody's interested in these, please let me know.

Programming DEC LQP02/LQP03 printers

LQP02/3 being daisy wheel and obeying the rules of inerta and acceleration are like band printers in that some sequences will print slower (less than max speed). The is especially true if the carriage positioning commands are used. So speed specs used a standard text and line width so that comparison could be made. Allison Allison

It would work for microvax but I dont have any drivers for that. The basic board is a pair of AY-mumble sounds chips from GI. What I need now (or to do) is a composition to performance compiler that would allow editing input and running it for the ear. Allison

Maybe this just shows that I'm too much of a crypto geek, but anyway: "Shannon text" means that the letters are distributed in a way typical for English-language plain text. i.e. the typical ETAOIN... distribution. Depending on the context, it may also imply a "typical" distribution of word lengths too. This actually matters for chain printers (where you can choose a subset of letters that go on the print chain and get better performance), but it's not such a big deal for dot-matrix or laser printers which tend to print at the same speed (until something overheats, at least) no matter what. -- Tim Shoppa Email: shoppa(a)trailing-edge.com Trailing Edge Technology WWW: http://www.trailing-edge.com/ 7328 Bradley Blvd Voice: 301-767-5917 Bethesda, MD, USA 20817 Fax: 301-767-5927

Because the LQP 02/03 use different sequences from the later LA series dotmatrix printer that can do them. You will need manuals for LQP02 and 03 for a detailed descritption as by time the ln03 was sold those old LQPs were gone. Allison

Programming DEC LQP02/LQP03 printers

by flo＠rdel.co.uk

Could anyone help me out by looking up some programming information for a DEC LQP02 or LQP03, please? I'm working from an LN03 manual that happens to mention that the following control sequences exist on letter-quality printers, but it doesn't give details. I'd like to know how to invoke: DECFIL (Right Justification) DECFPP (Positioning) DECPSPP (Print Specified Printwheel Position) DECPTS (Printwheel Table Select) DECSS (Set Space Size) DECUND (Programmable Underline Character) While I'm on the subject, I see that the Terminals and Printers Handbook 1983-84 entry for the LQP02 says that it prints "32 char/s (letter-quality, Shannon text)". Does "Shannon text" mean anything to anyone? Cheers, Paul
