SDF Beget's ICM - Interim Computer Museum

by Clem Cole

Please excuse the wide distribution, but I suspect this will have general interest in all of these communities due to the loss of the LCM+Labs. The good folks from SDF.org are trying to create the Interim Computer Museum: https://icm.museum/join.html As Lars pointed out in an earlier message to COFF there is a 1hr presentation on the plans for the ICM. https://toobnix.org/w/ozjGgBQ28iYsLTNbrczPVo FYI: The yearly (Bootstrap) subscription is $36 They need to money to try to keep some of these systems online and available. The good news is that it looks like many of the assets, such as Miss Piggy, the Multics work, the Toads, and others, from the old LCM are going to be headed to a new home. ᐧ

Interesting history of Bell Labs

by Dan Cross

Steve Bellovin just posted this on Mastodon, I thought it might interest some folks here. It's more about Bell Labs than Unix, but of course Unix, as a product of Bell Labs, is related and is mentioned. - Dan C. https://www.construction-physics.com/p/what-would-it-take-to-recreate-bell

UNIX Roff Manual

by segaloco

Just sharing a copy of the Roff Manual that I had forgotten I scanned a little while back: https://archive.org/details/roff_manual This appears to be the UNIX complement to the S/360 version of the paper backed up by Doug here: https://www.cs.dartmouth.edu/~doug/roff71/roff71.pdf From the best I could tell, this predates both 1973's V3 and the 1971 S/360 version of the paper, putting it somewhere prior to 1971. For instance, it is missing the .ar, .hx, .ig, .ix, .ni, .nx, .ro, .ta, and .tc requests found in V3. The .ar and .ro, and .ta requests pop up in the S/360 paper, the rest are in the V3 manpage (prior manpages don't list the request summary). If anyone has some authoritative date information I can update the archive description accordingly. Finally, this very well could be missing the last page, the Page offset, Merge patterns, and Envoi sections of Doug's paper are not reflected here, although at the very least, the .mg request is not in this paper so the Merge patterns section probably wasn't there anyway. - Matt G.

When did "man cal" lose the comment about 1752?

by Douglas McIlroy

> Yeah, but if you do that you have to treat the places > acquired in the Louisiana Purchase differently because > they switched in 1582. And Puerto Rico. Bleh. Then there are all the German city states. And the shifting borders of Poland. (cal -s country) is a mighty low-res "solution" to the Julian/Gregorian problem. Doug

When did "man cal" lose the comment about 1752?

by Dave Horsfall

The manpage for "cal" used to have the comment "Try September 1752" (and yes, I know why); it's no longer there, so when did it disappear? The SysV fun police? I remember it in Ed5 and Ed6, but can't remember when I last saw it. Thanks. -- Dave

Reference Cards for PDP8, PDP9, PDP-10, PDP11, TOPS-10

by Clem Cole

A few folks on the PIDP mailing lists asked me to put scans of the cards I have on-line. I included TUHS as some of the new to the PDP-11 folks might find these interesting also. I also included a few others from other folks. Note my scans are in 3 formats (JPG, TIFF, PDF) as each has advantages. Pick which one you prefer. I tried to scan in as a high a resolution as I could in case some one wants to try to print the later. I may try adding some of my other cards, such as my microprocessor and IBM collections. In the future https://drive.google.com/open?id=13dPAlRMQEwNvPwLXwlOC5Q_ZrQp4IpkJ&usp=driv… ᐧ

Puzzled about COFF

by Douglas McIlroy

I subscribe to the TUHS mailing list, delivered in digest form. I do not remember having subscribed to COFF, and am not aware of how to do so. Yet COFF messges come in my TUHS digest. How does COFF differ from TUHS and how does one subscibe to it (if at all)? Doug
