(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.

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

>Hey, that's all the more on-topic here, as (s)he performed music using >a PDP-11! Is anyone else here (John W., does this still interest >you?) interested in using PDP-11s for music/sound synthesis. I'm interested... I have a couple of Casio CZ-101s that I would love to drive using the pdp-11. Allison modified a DLV11-J for me years ago so that I could control some devices... but as I am moving my entire collection to storage (my partner and I are looking into getting a house with a garage and basement so I can have a real museum), I'm not sure where it is right now. Also, years ago I built a device with several of the TI Sound Generation Controllers on it, controlled by a DL11-C. I had some software which played the music files produced by the music compliler written at Stanford. I still have the device, though I've misplaced the schematics for it...

Woz and his 6 chips...

FYI, Woz even talked about how he thought that his 6-chip design was one of his most brilliant ideas, in an interview in Byte in 1984... Will J ________________________________________________________________________ Get Your Private, Free E-mail from MSN Hotmail at http://www.hotmail.com
