Fwd: [simh] Announcing the Open SIMH project

by Clem Cole

Announcing the Open SIMH project SIMH is a framework and family of computer simulators, initiated by Bob Supnik and continued with contributions (large and small) from many others, with the primary goal of enabling the preservation of knowledge contained in, and providing the ability to execute/experience, old/historic software via simulation of the hardware on which it ran. This goal has been successfully achieved and has for these years created a diverse community of users and developers. This has mapped to some core operational principles: First, preserve the ability to run old/historically significant software. This means functionally accurate, sometimes bug-compatible, but not cycle-accurate, simulation. Second, make it reasonably easy to add new simulators for other hardware while leveraging common functions between the simulators. Third, exploit the software nature of simulation and make SIMH convenient for debugging a simulated system, by adding non-historical features to the environment. Fourth, make it convenient for users to explore old system environments, with as close to historical interfaces, by mapping them to new features that modern host operating systems provide. Fifth, be inclusive of people and new technology. It's serious work, but it should be fun. Previously, we unfortunately never spent the time to codify how we would deliver on these concepts. Rather, we have relied on an informal use of traditional free and open-source principles. Recently a situation has arisen that compromises some of these principles and thus the entire status of the project, creating consternation among many users and contributors. For this reason, a number of us have stepped up to create a new organizational structure, which we call "The Open SIMH Project", to be the keeper and provide formal governance for the SIMH ecosystem going forward. While details of the structure and how it operates are likely to be refined over time, what will not change is our commitment to maintaining SIMH as a free and open-source project, licensed under an MIT-style license as shown on the "simh" repository page. It is our desire that all of the past users and contributors will come to recognize that the new organizational structure is in the best interests of the community at large and that they will join us in it. However, this iproject as defined, is where we intend to contribute our expertise and time going forward. At this point, we have in place the following, although we foresee other resources being added in the future as we identify the need and execute against them: A Github "organization" for the project at https://github.com/open-simh A Git repository for the simulators themselves at https://github.com/open-simh/simh The license for the SIMH simulator code base, found in LICENSE.txt in the top level of the "simh" repository. The "SIMH related tools" in https://github.com/open-simh/simtools. This is also licensed under MIT style or BSD style open source licenses (which are comparable apart from some minor wording differences). A "SIMH Steering Group" -- project maintainers and guides. The conventional git style process is used for code contributions, via pull request to the project repository. The Steering Group members have approval authority; this list is likely to change and grow over time. By formalizing the underlying structure, our operational principles and guidance can best benefit the community. These are being developed and formalized, with a plan to publish them soon. We have used our best judgment in setting up this structure but are open to discussion and consideration of other ideas, and to making improvements. Many of us have been part of different projects and understand that past mistakes are real. We have tried to learn from these experiences and apply the collected wisdom appropriately. We desire to hear from the community as we update and refine the operating structure for the Open SIMH project. We hope for your patience and look forward to your support as we work to refine the organization and be able to provide this wonderful resource for anyone to use as we continue to evolve the technology provided by the SIMH system. The SIMH Steering Group Clem Cole Richard Cornwell Paul Koning Timothe Litt Seth Morabito Bob Supnik ᐧ ᐧ ᐧ

Please move the SIMH discussion to COFF

by Warren Toomey

Hi all, I think it's time to move the (no longer) SIMH discussion over to the COFF mailing list. The S/N ratio is dropping and we are straying too far away from the Unix side of things. Many thanks! Warren

Re: [TUHS, groff] 1981 edition of AT&T Nroff/Troff User's Manual

by Douglas McIlroy

> https://www.tuhs.org/Archive/Documentation/Manuals/Unix_4.0/Volume_1/C.1.2_… Since PDF didn't exist in 1981, the document is either a scan or the result of a recent *roff run on ancient source. If it was made from source, it's an impressive testimonial to the longevity and stability of troff. Most probably it's a scan, in which case we owe many thanks to the public-spirited person who digitized this trove. Was it you, Arnold? Doug

On Jun 3, 2022, at 4:48 PM, Larry McVoy <lm(a)mcvoy.com> wrote: > Um, so there were 3: 386, Net and Free. That's already 2 too many. My recollection matches what Warner is saying. NetBSD & FreeBSD got going *because* 386BSD was effectively frozen. It wasn't dead dead but patches were not being upstreamed (as we say now), and so on. I do agree with you that even two variants were 1 too many. But even one would probably not have mattered as the AT&T lawsuit was a huge cloud on *BSD's popularity. As well as there were other factors. Linus and Linux had a much better story, its development was more nimble, with many younger and much more enthusiastic developers/users etc. Not that anyone really cares at this point except some graybeards! The Open SIMH project sounds great!

Historical application software

by Paul Ruizendaal

I came across a website that discusses reviving an old binary for Lotus 1-2-3 for SysV Unix (386 COFF), on the way to making it run on Linux: https://lock.cmpxchg8b.com/linux123.html The audience here may enjoy the read, and maybe it is of use when reviving other old application software for 1980’s and 1990’s Unix. The key part I think is this: Quote: "Yikes - it’s an original unstripped object file from 1-2-3. There are nearly 20,000 symbols including private symbols and debug information. Why would Lotus ship this? It’s so big it must have required them to phyiscally ship an extra disk to every customer? Could it have been a mistake, accidentally left on the final release image? I had so many questions, but I’m not old enough to have any experience with SysV, so I asked the greybeards on alt.folklore.computers if they had seen this before and why this might have happened. The answer was that this is probably deliberate - dlopen() was not widely available on UNIX in the early 90s, so there was no easy way to load native plugins or extensions. To solve this, vendors would ship a bunch of partially linked object files with a script to relink them with your extensions – Clever!"

Re: Anyone have an interest in really old analog multimeters and a vacuum tube tested circa 1960s or 1950s?

The party also has a vintage AUTOMOBILE tester If anyone knows of a car collector with a passion for such things interested in a display piece Or if you still have the first car you ever bought sitting in the garage Link to posting attached. https://cnj.craigslist.org/zip/d/hightstown-for-scrap-vintage-eico-888/7489… I am in direct contact with the party offering these items.

Why is it always "fast boot" in 2.11BSD?

by Matthias Bruestle

Hi, I have noticed, that 2.11BSD is in all cases where I looked set to "fast boot", which AFAIK means no fsck of at least /. I found nobody talking about this or providing information about how to change it to "slow boot" with a proper check, which is now normal. Is there a reason why it is not possible to deactivate fast boot? Or is it just that nobody bothered to do it? Thanks Matthias -- When You Find Out Your Normal Daily Lifestyle Is Called Quarantine

ACM opens up much of its archives

by Douglas McIlroy

>> If you’re a *current* member of these societies then you should have good access to journal content. >I believe this is true for ACM, but for IEEE not so much. You have to pay for a digital library membership _in addition to_ your standard membership ACM is the same. At $99/year membership is a bargain by ordinary professional society standards. But they charge an additional $99 for access to 21st-century Digital Library.content. Doug
