DECUS SIG newsletters, including RSX11/IAS Multi-Tasker, DeVIAS, BASIC, Datatrieve, Networks...and others.

  Back in the day, when the earth was young and rock and roll ruled the airwaves, not too long after we slew the dinosaurs with our mighty slide rules, there was an operating system called RSX11M. There was also one called RSX11D, and one called IAS,but no one seems to remember much about them - but that's another story.

  It had an enthusiastic and devoted following. The faithful all read a newsletter from DECUS called "The Multi-Tasker". It was kind of like a fanzine for PDP11 system programmers. And DECUS Symposia were a lot like SF Cons, but, that too, is another story.

  This was long before there was a World Wide Web, where everything is online and freely downloadable. You would subscribe to the Multi-Tasker, and it would be brought to you every month (well, more or less) by a uniformed representative of the Federal Government.

  Those days are long past, as are the RSX family of operating systems, and PDP11s for that matter. But there was much wisdom in these newsletters (there was also much humor, drama and low cunning in these newsletters) that is still of value to the DEC historian and RSX11 hobbyist. I recently had to look for an article in one that I didn't have in my collection, and it took a middin' slug of effort to find it (thanks again, Alan Frisbie).

 There are some issues available on assorted RSX DECUS symposium tapes (a pretty good number of the 1984 and newer are there), and a goodly slug of several years of  them are on Bruce Mitchell's Machine Intelligence and Industrial Magic web site. but many issues are not to be found anywhere online.

  I decided to scan in my collection of DECUS SIG newsletters (Multi-Taskers and others as well)  and have them online here, in case any other hobbyists have a need for them. I'll update this entry as I get them done. These aren't done to the standards of Bitsavers - I just used the scanner built into my wife's printer - but, they're better than nothing...scanning documents is a bit of a pain in the sitz-platz - I have even more appreciation for the work done by Al Kossow than I did before starting this.

Let's start with the DeVIAS Letters (named for the Delaware Valley IAS LUG). I only have a few later issues. I'd really like to find some more.. If you have any you'd like to part with, or loan to me for scanning,  please let me know....

At times, the DeVIAS Letter and the Multi-Tasker were combined into one newsletter - most
likely due to the fact that IAS was being discontinued, and most IAS sites were going to
be switching to RSX.

Here's some Mini-Taskers, the newsletter of the RT11 SIG. RT-11 is OK - I use it on my old PDT-11/150s, but it feels a little limited when compared to RSX.

December 1984    This ish had a great article on RT-11 internals.


Here's some BASIC SIG newsletters. Some of these have art from Vaughn Bode's JUNKWAFFEL comics.

  The BASIC SIG morphed into the Commercial Languages SIG, which include BASIC, COBOL and DIBOL. They still had plenty of Vaughn Bode's art, though.

  The Cache Buffer was the newsletter of the RSTS SIG. RSTS is a pretty good timesharing system. I never really warmed up to it because it was more user oriented - unlike RSX and RT, you didn't get a chance to work with the internals much. IAS, RSX and RT, you were practically invited to roll up your sleeves and start writing internals code.

The Newsletter of the Large Systems SIG (big 36 bit systems), At Large.

March1984  This issue was after DEC announced the end of the 36 bit systems.
April 1985    This issue celebrates the 20th anniversary of the SIG.
June 1985   This issue contains the story "Alice's PDP-10". It's funny.

  The Office Automation, Personal Computer, Graphics, COBOL and DIBOL SIGs got lumped together into a single newsletter. Makes sense...sort of. I guess. It's interesting to read all of the optimistic talk about DEC's plans for Personal Computing....

  The UNIX SIG, UNISIG, newsletter was called "Toolkit". To be honest, I loathe UNIX with the white hot incandescence of a galaxy full of exploding supernovae,  but, I have the newsletter, so here it is....

April 1984


  The Languages and Tools SIG had a newsletter called "The Heap".
