Computer flooring/flooding/water in computer rooms

by pete＠dunnington.u-net.com

On May 28, 12:57, McFadden, Mike wrote: > Flooded computer room We had a similar problem, thanks to our aircon, a year or so ago. Our big aircon is one that has dehumidifies the air, then cools it, and finally rehumidifies it if necessary so it's not too dry (which encourages static buildup). Well, a valve jammed, and the rehumidifier section filled up with water and overflowed. We ended up with an inch-deep pool of water over about half the floor -- not as serious as Mike's incident, but still a bit messy. And dirty. What alerted us to it initially was the smell of dampness :-( -- Pete Peter Turnbull Network Manager University of York

Qwint Systems?

by sloboyko＠yahoo.com

Can anybody tell me anything about these? Found a little something I thought was word processor, but it actually looks like some sort of serial terminal using 80 column paper for output vs. a CRT. Very compact, kind of a neat looking little package. Googling has come up dry..... What you probably have is a Qwint 740 or 780 (I'd have to see it to know what model). It was the smallest plain paper teletype replacement probably ever built. I worked there at Qwint (formerly Martin Research of 1970's MIKE 8008/8080 fame) between '84-85; I wrote the service manual (which I think I still have). It's a very sophisticated machine-don't let the size or apparent simplicity fool you; it uses a Z-80 with bank switching! It is possible to reink the ink cartridge via the old WD-40 trick; don't lose it because they are made of unobtanium. The company was bought by Zebra (who makes the thermal bar code printers), mostly for IP (intellectual property). ===== -Steve Loboyko Incredible wisdom actually found in a commerical fortune cookie: "When small men cast long shadows, then it is very late in the day."

PDP-8 stuff

by ggs＠shiresoft.com

I'm looking for information on the expansion boxes for the "older" PDP-8's (ie 8/I and 8/L). Specifically: BA08A BM12L MM8I Ideally I'd like to find user's manuals and maintenance manuals for them, but at this point anything would be useful. Of course, I'll also re-iterate my call for information on the DF32D also. Thanks. -- TTFN - Guy

GE Terminet terminal

by jpl15＠panix.com

What is being described is almost surely a Terminet - an ASCII teleprinter using a continuous rotating band with upright 'fingers' containing the individual characters - these passed in front of 72 hammers, and behind them were the ribbon and paper respectively. There were three complete sets of character fingers, thus cutting the 'latency' of the band in thirds. When the right character arrived at the correct position on the page, the opposing hammer fired and imprinted it. The fingers were easily removable allowing for alternate fonts and character sets. The two I had were fitted with the dual cassette units (used instead of paper tape, (but employing very much the same 'algosithm'), and I used them in the very early 80s with a 300 Baud Novation JCat modem, to access Compuserve and a couple of other primitive on-line services, as well as BBSes. The unit is well worth saving - you don't say where you are, but they are rare now and I'm sure someone will be very happy to make it go away for you... Cheers John

DEC VT102 terminal question?

by jwest＠classiccmp.org

I have a DEC VT102 terminal that I got some time ago from a listmember. On the right of the keyboard where the numeric keypad is, the keys don't match the color of the other keys on the keyboard. The upper left key in the keypad is gold, and the other keys on the keypad are different colors - red, blue, white - and have editing words on them, I think words like "left, copy, print", something like that. My question is - is it likely that someone scavenged keys from another non-vt100 keyboard to replace missing keys, or was this some option used with some word processing software? If the later, I'm happy I have something unusual. If the former, I am going to yank those keycaps off and scavenge the "correct" keys from one of the other VT100's I'm going to junk. Anyone know the answer? Thanks! Jay West --- [This E-mail scanned for viruses by Declude Virus]

selectric consoles

by akb+lists.cctech＠imap1.mirror.to

I think Selectrics are pretty cool; I'd kinda like one I could use as a printer, and if it could be a full serial tty that would be even cooler. So far, I've found that IBM made the 1050 and the 2741 selectric-based console terminals, both of which were large, heavy, and not very reliable. Did IBM ever do any better, like say a serial module for a selectric III? I know some of the Wheelwriter typewriters had serial ports, but the golf ball type elements are just too much cooler. I found some web pages that talk about Trendata ttys based on selectrics, but very little hard info; anyone here know anything about them? I also remember the ByteWriter and similar contraptions that strapped a bunch of solenoids on top of a typewriter keyboard, but while entertainingly kludgy, that lacks a certain degree of elegance. --akb

Anyone have a working paper tape reader?

by bob＠applegate.org

I'm trying to resurrect a copy of Tom Pittman's 6502 Tiny Basic. Tom has paper tapes of the binaries, and was willing to send me one in exchange for reading the tape and sending him back some sort of machine-readable version of the contents. Not having a paper tape reader, this would be a long, dragged-out process of my manually converting the entire tape to binary by hand. Is there anyone in the US that could do this for Tom? He might be happy just to have the binary version (or the raw text) emailed to him. If you can help, please let me know. Bob
