I wasn't involved with this, but my recollection from dribs and drabs I overheard was that DoE got a copy because they'd been the funding agency for a lot of the work - i.e. MIT didn't just give a copy to DoE, it was a requirement.

Modems & Xerox

by c.murray.mccullough＠gmail.com

I started accessing BBSs back in the early 70s with a 300 baud modem. >From there it went to 1200; 2400; 9600; 28.8K and 56Kilobaud. All on dialup! Now at 5 Mbits/sec. here in Ontario. An American friend has 250Mb/s download. Yikes! The classic computer era taught us patience didn?t it? BTW, one had to have a private phone line not a party line for a modem to work. Making our hobby more expensive! On the business-side of computing: Xerox sold 50.1% of its business to Fujifilm, Japan. Xerox Parc was a seminal institution in early classic computing era: Mouse and graphics input for instance. Happy computing! Murray :)

X11 expertise on ancient HW sought... (4-plane visual (overlay) via X-server on MS-WIndows)

by dimitris.theo.gr＠gmail.com

Sorry for undiggind this subject so many years later, but have you found a solution to your problem? I am facing exactly the same issue, and i have tried all possible windows X server options without success. The only possibility I am working with is with a Mac OS X server, which reports a 5-bit visual.

SuperTerm Maintenance Manual

by mike_t_norris＠hotmail.com

Hi Guys, I am new to the group, so let me know if this post is inappropriate. I have a SuperTerm Maintenance Manual that I am about to put in the bin. I am prepared to scan it if any one is interested, I could not find it on bitsavers.org, but I guess there may be one in the backlog? The SuperTerm was manufactured by Intertec Data Systems c. 1978, it was a 180 CPS dot matrix printer (RS232), quite often used as a console printer in place of a LA36, Intertec also did a speed up board for the LA36 (I may have details on that when I get through clearing out my loft), to make it a 150 CPS printer, although it was prone to carriage slams initially, same was true of the SuperTerm for a while, which also resulted in the carriage driver transistors burning out. The company I worked for produced a separate driver board to get around the problem, typical patch at the time. Regards Mike Norris

Foonlies

by lars＠nocrew.org

This document seems to imply that the Super Foonly and the Foonly F1 were separate machines. When I've seen them discussed, they always seemed to be uses synonymously. http://www.bitsavers.org/pdf/dec/pdp10/KC10_Jupiter/memos/foonly_19840410.p… SUPERFOONLY DESIGNED 1968-71 10,000 TTL IC'S 3 MIPS F1 (1978) 5,000 ECL IC'S 3.5 MIPS Also, except for the CCRMA F4 at Computer History Museum, does anyone know about any Foonly machine having been preserved?

connecticut micocomputer AIM16

by billdegnan＠gmail.com

Does anyone have an AIM16 hardware unit made by Connecticut microComputer company, from the late 70's? I am working through their cassette software, a box I got years ago from their internal programming department with versions and variations of same programs. Bill

DL10 documentation

by jnc＠mercury.lcs.mit.edu

> From: Phil Budne > FWIW, Found these bits > ... > Those bits and others can be found Excellent archaeology! With these, and the ITS sources (for which we have both the -10 and -11 sides), the register definitions in the early PDP-10 CPU manual, and the prints, it should be possible to write a programming manual for the DL10, to replace the one that's now lost. (If it ever existed - does anyone know?) Any chance I could convince you to enter all this stuff on the CHWiki DL10 article: http://gunkies.org/wiki/DL10 Lars (mostly) and I have added a little bit, but there's still a long way to go! Noel
