Well, I found an 11/03 at a customer and he said 'take it if you want...' which, of course I did. He said it was a spare bootsystem for their (long gone) VAX 785. It has a bit of an odd card in it, almost empty with 50 pin connectors on it and just a few chips on it. I guess this went into the VAX to boot/load the microcode?

I don't have an OS/8 system up and running right now, but OS/8 itself only keeps dates in that format. It has two additional bits stored at another location, which tells how the year is to be interpreted. I would suspect that TECO8 just sets the 13th bit if the two "century" bits in OS/8 is non-zero. So, years higher than 1977 are actually encoded as 4096+((year-1970) mod 8). Which, incidentally, is also exactly what the documentation you quote is saying... :-) Johnny -- Johnny Billquist || "I'm on a bus || on a psychedelic trip email: bqt at softjar.se || Reading murder books pdp is alive! || tryin' to stay hip" - B.

Xerox 820 Keyboard for parts?

by gm10＠consulnix.com

Hi, Been lurking for a month or two, and have been enjoying the conversations. I was curious if anybody had a Xerox 820 keyboard laying around that wasn't needed. Or parts to one. I have one that needs a switch replaced. Ideally, a right CTRL key would be handy too, but I might be able to salvage mine. The keyboard assembly is made by Maxi-Switch Co. with a PN of 630107-02. I don't have a PN for the switches themselves, but they look like this: https://dl.dropbox.com/u/489067/test/20120709_154136.jpg Thanks in advance! Garrett Meiers

Tnix a.out

by aek＠bitsavers.org

Looks like Tnix has a normal PDP-11 a.out. dd copied over ran OK and the stock dd.c from the V7 source distribution compiled and ran. Discovered more tools that are missing (like nm and strip) This is interesting because the Tnix cross-development tools I've recovered (and that others might have on floppy) should be able to be run under SIMH. So if there are old development project sources floating around, they should be rebuildable without a 856x

The National Air and Space Museum's Space History and Education divisions, in collaboration with the French Embassy, will host a symposium to commemorate the 50th anniversary of the Telstar satellite, representing the birth of global telecommunications. The symposium will be presented in two parts. The first is a half-hour satellite television connection between the Museum and the Pleumeur-Bodou Tele communications Museum in France to commemorate the first global transmission of a television signal. Speakers include Secretary of the Smithsonian Wayne Clough and French Ambassador to the United States Fran?ois Delattre. The second part of the symposium features three sessions, with historians and experts from industry and government, discussing major aspects of the Telstar project and its impact on the development of global communications. The event also will include footage from the original 1962 broadcast. Telstar 1 launched on July 10, 1962 from Cape Canaveral and was the first privately sponsored spacefaring mission. It handled a variety of transmissions, including telephone, fax, data, still pictures, and television signals, from several locations across the United States and Europe. Additional information on the program and the history of Telstar, is available on a _website_ (http://telstar50.org/) developed by the Embassy of France.

any VT525 terminal users? with LCD?

by chrise＠pobox.com

I saved a couple DEC VT525 terminals a year ago or so from a barn and after cleaning them up, they seem to work mostly with the exception that the video they produce on a number of different VGA LCD panels is quite dim. Both terminals exhibit the same issue each on a number of different LCD panels-- so I'm a little hesitant to blame something wrong with the terminals and rather wonder about the VGA-ness of the signal they produce. I gather from the specs that it should be producing a 800x480 @ 73 Hz signal. My monitors claim to do that and don't complain in any way... other than that the video is pretty dim and washed out. Is there an existance proof of one of these working with a modern (3 or 4 yr old) VGA LCD panel or were they only successful with pre-LCD CRT monitors for some reason? Chris -- Chris Elmquist

PDP-11 Wiki

by reiche＠ls-al.eu

Hi all, I responded to a post on the SimH mailinglist, asking about why there was no PDP-11 Wiki where bits and pieces or whole articles and papers could be found, concerning the PDP-11. I thought it was a good question, considering I love the Richard's Terminal Wiki out there. So I quickly installed one and it is in pristine vanilla state at the moment. I can't be bothered with filling it with actual content, as I am still a total and complete noob on PDP-11's but will contribute whenever and where-ever I can. My job will be moderating the stuff for the time being. Have at it people! http://pdp-11.ls-al.eu re, Sander

I see from the manual on Bitsavers that the monitor gets a composite video signal, and that the keyboard uses 4800-baud 8-N-1 RS423 signalling. Is the protocol described anywhere? 2. I found a box with three option cards: 2 x 000046 and 1 x 000401. What are these? Thanks, Camiel.

Sadly, there is the same problem here. A lot, if not most, of the primary and secondary school teachers-to-be here do not know even basic mathematics. The University here (the one which produces engineers and Ph Ds in engineering, physics and chemistry) added an extra year to the M Sc courses long ago, so as to allow the students to catch up with the maths and physics. Even in the early 1970s, the curriculum in the UK up to O-levels was at least a year ahead of that here in Sweden; I went to a school for a year in Yorkshire when I was 15 (5th form) and during that one year I had to catch up with half the 4th form maths and physics, in addition to doing the 5th form syllabus and taking O-levels. When I came back I learned no new maths, physics or chemistry for the 3 years at school here until I went to University. I should have stayed on in England. /Jonas
