> From: Dave Horsfall > What does "cal 9 1752" show on your boxes? Given that the source: https://minnie.tuhs.org//cgi-bin/utree.pl?file=V6/usr/source/s1/cal.c has been in C since at least V6, I'd be rather surprised if on other machines it did anything other than what those of us who were paying attention read in the documentation: https://minnie.tuhs.org//cgi-bin/utree.pl?file=V6/usr/man/man6/cal.6 back then: "Try September 1752." Get off my lawn. Noel PS: Said documentation already notes that it won't work in most counries: "The calendar produced is that for England and her colonies."

Thank you, Doug.

DECUS started out the same way. For instance, many/most PDP-10 OS's used the DEC compilers and often even found a way to run TOPS-10 binaries by emulating the UUOs. The IBM/360 world worked pretty much the same way. My own experience was that the compilers (e.g WATFIV-FTNG-ALGOLW-PL/1) and language interpreters (APL-Snolbol) for the TSS and MTS had been 'ported' from the IBM-supplied OS [my own first job was doing just that]. The same story was true for the PDP-8 with DOS-8/TSS-8 and the like. By the time of the PDP-11, while some of the DEC source code was available (such as the Fortran-IV for RT-11/RSX), since it took at PDP-10/BLISS to support it, DEC had it its protection - so moving it/stealing it - would have been harder. By the time of the VAX, DEC was charging a lot of money of SW and it was actually a revenue stream, so they keep a lot more locked up and had started to do the same with PDP-10 world. So, the available/unavailable source issue came when things started to get closed up, which really started with the rise of the SW industry and making revenue with the use of your SW. OEMs and IVSs started to be a lot less willing to reveal what they thought was their 'special sauce.' Some/many end-users started to balk. RMS just took it to a new level - just look at how he reacted to Symbolics being closed source :-) The question that used to come up (and still does not an extent) is how are the engineers and teams of people that developed the SW going to be paid/renumerated for their work? The RMS/GNU answer had been service revenue [and living like a student in a rent-controlled APT in Central Sq]. What has happened for most of the biggest FOSS projects, the salaries are paid for firms like my own that pay developers to work on the SW and most FOSS projects die when the developer/maintainer is unable to continue (if not just gets bored). In fact, [I can not say I personally know this - but have read internal memos that make the claim], Intel pays for more Linux developers and now LLVM developers than any firm. What's interesting is that Intel does not really directly sell its HW product to end-users. We sell to others than use our chips to make their products. We have finally moved to the support model for the compilers (I've personally been fighting that battle for 15 years). So back to my basic point ... while giving the *behavior* a name, the *idea *of "Open Source" is really not anything new. While it may be new in their lifetime/experience, it is frankly at minimum a sad, if not outright disingenuous, statement for the people to try to imply otherwise because they are unwilling to look back into history and understand, much less accept it as a fact. Trying to rewrite history is just not pretty to witness. And I am pleased to see that a few folks (like Larry) that have lived a little both times have tried to pass the torch with more complete history. Clem. ᐧ

Re: [COFF] [TUHS] head/sed/tail (was The Unix shell: a 50-year view)

by Lars Brinkhoff

Moved to the COFF list. > Yes, WAITS is what I was thinking of. As I mentioned in my previous > mail, it feels like the SAIL timesharing systems get mentioned briefly > in a lot of accounts of historical computing, sometimes with mention > that they had some sort of (relatively) advanced video terminals, but > no in-depth descriptions of the actual hardware/software environment. I agree WAITS gets very little attention, particularly in relation to the great number of things pioneered at SAIL. I'm involved making emulators for some of the hardware. SAIL started out with a couple PDP-1 timesharing systems with vector displays from Philco. But that's almost a pre historical era. The PDP-6/10 started with another vector system from III. It could support up to 12 displays, but only ever had 6. A raster display system was added in the early 70s. It must have been one of the very first bitmapped display systems. It came from the Data Disc company and used disk for storage. It was dual ported: the computer could write data, and the displays could read. 64 displays were supported. The III and DD displays used the SAIL keyboard which introduced the META key. The Data Disc displays and SAIL keyboard heavily influenced Tom Knight at MIT to make a similar system for their AI lab PDP-10 running ITS.

On 14 Jul 2021 22:21 -0400, from douglas.mcilroy(a)dartmouth.edu (Douglas McIlroy): > IBM provided source code for the Fortran II compiler. More recently than that, for the original IBM PC anyone could get (I believe) the complete schematics, detailed technical information, and a commented ROM BIOS source code listing just by purchasing their Technical Reference for, what, $50 or thereabouts? It certainly wasn't open source according to the Open Source Definition, but it certainly was _available_ to anyone who wanted a copy. What kind of company does that today, in a similar market segment? -- Michael Kjörling • https://michael.kjorling.se • michael(a)kjorling.se “Remember when, on the Internet, nobody cared that you were a dog?”

quick question

by Jesse Davidson

Hi Stephen, I noticed you shared an article from KiCAD.org when you talked about PCB design software tools, here: https://minnie.tuhs.org/Blog/2019_06_18_cscvon8_lessons_learned.html I thought that the article from KiCAD.org is actually pretty good, but we recently published an article that goes much deeper and talks about the ten best PCB design software tools in 2021. PCB design software is the operating program used by a computer that helps electronic engineers design printed circuit board (PCB) layouts. This design tool helps users to collaborate on various projects, access libraries of components created before, know the accuracy of their circuit schematic design, and more. The article talks about the best PCB design software tools available in the market today and provides answers to the following questions: - What is PCB design software and why do you need it? - What is the evaluation criteria for PCB design software? - What are the key features to look for when choosing PCB design tools? - What are other recommended PCB design software tools? We quote 30 different sources in the article -- it's quite authoritative. Here's the article, if you're interested: https://www.wellpcb.com/special/pcb-design-software.html Would you consider sharing our article with your readers by linking to it? Anyone who is looking for the right PCB design software to use might find this very useful. Please let me know if you have any questions and thank you for your time. Cheers, -Jesse -- Jesse Davidson, Editor 5 Ross Rd Durham, NH 03824 BTW, if you didn't like getting this email, please reply with something like "please don't email me anymore", and I'll make sure that we don't.
