(OT) firmware, manual, schematics, etc re copyright comments

by sanepsycho＠globaldialog.com

First thing a discussion copyright probably does belong on this list since people are discussing making copies of manuals, scematics, eproms, paper tapes, etc to preserve and keep old systems running and all these fall under copyright and reproducing them is a infringe of copyright without the author's consent even if it is done for non-commercial purposes under current US law. ... now my rant ... Companies generally are not interested in maintaining their old copyrights and preserving them, in the vast majority of cases old works are is only maintained by dedicated people like hobbyists, scholars or librarians. This is why "hard copyrights" like we have with the DMCA with encryption and digital restrictions entering firmware and severe criminal or civil penalties for *any* violation, without the character of the infringement even being considered. This is very wrong. Before 1973 the owners of a copyright had to actively acquire it by first claiming copyright on the work and second by registering their copyright to keep it active after the initial 28 years. Before the "No Electronic Theft Act" in 1996(7?) it was not considered infringement to reproduce works as long as the work was not being actively maintained i.e. publicly available and the reproduction was not done for profit. So if I had a copy of a manual or schematic for an old piece of equipment I was free to make a copy and give it to you as long as I did not profit directly from the act. There is no logical reason that many technically infringing uses of abandoned copyrights should be perfectly legal as long as it is not for profit. If your argument to refute this is that the author has a right control of the work, I would say that this right is not absolute since it is legal for me to make a dub of a CD for my car, to sing happy birthday (still copyrighted) at a birthday party in my home, and to record TV off the air without having to pay royalties to anyone. I see it as once an author makes a works publicly available, additional non-commercial uses should fall into fair use if the author does not continue making the work available to the public to prevent useful works >from disappearing. My point is that anybody trying to maintain/restore an old piece of equipment is almost certainly violating copyrights if they have had to rely on information reproduced by anybody other than the copyright holder. Thus under US law, as it stands, you are as guilty as anybody who has use NAPSTER, KAZA, etc to download music, and if you want to continue your hobby you should write your representative to get the laws changed to put some reasonable exclusions to infringement. ::sigh:: OK, I have that off my chest for now.

Let me know if you need detailed tech data; I have the Fairchild Data and Application Books and the Signetics Data Book. I even have a fair bit of 9300 ICs, but alas, no 9311s and only the regular power 9314. Probably no 8273s but I can have a look. Good luck & thanks again for all YOUR help! mike

Apple 1 schematics

by cb＠mythtech.net

>A: Yes. >B: Google is your friend. Oh look at that... tons of hits. Gee, I figured it might be the kind of thing that Apple would have protected... maybe it was the thread on copyrights just soured me into forgetting that not everything in this world is locked away in a vault. >It's *extremely* difficult to find some of the Apple I parts, which have >been out of production for over years. Particularly the seven 1024-bit >MOS shift registers, and one hex-40-bit MOS shift register. Bummer! Maybe Tony will chime in with a list of readily available, drop it alternatives... or the plans to make replacements using common household cleaning products :-) >Not quite, since they had a PCB. (Unless you plan to lay out a PCB >yourself.) I really hadn't thought that far in advance.... I was honestly under the wrong impression that the Apple 1 plans would be hard to come by. -chris <http://www.mythtech.net>

VME CPU's: Documentation

by pat＠purdueriots.com

I'm wondering if anyone has documentation on my 68010-based MVME-110-1 CPU boards. Google doesn't help much. Is there a standard debugger that (should) be in its ROMs? Does anyone have an image available? I think that these boards might have a custom ROM image on them, but I'm not sure. Thanks for any help, Pat -- Purdue Universtiy ITAP/RCS Information Technology at Purdue Research Computing and Storage http://www-rcd.cc.purdue.edu

APOLOGY: Re: "Piracy" (was: Unauthorized copying

by cb＠mythtech.net

>Interestingly, the "Bill Gates Open Letter to Hobbyists", that is often >cited as being the origin of the word "piracy" being applied to software, >turns out to NOT use the word "piracy". It always helps to check >citations before relying on them. Someday, I'll learn to do so. I just read the letter... first time I ever have. I found two things that make me go hummmm: 1: MS Software is probably one of the highest pirated groups of software out there (no figures to back this up, its a wild assumption based on the fact that I know lots and lots of people that have various versions of Windows and/or MS Office, and haven't paid for all the copies they are running. Compounded by the vast market share, it seems that there is a good chance they rank at or near the #1 spot). Yet despite this, Mr. Gates seems to have done pretty well for himself. Actually, I have often wondered, if MS Software didn't get pirated, and every copy that every company and person ran was a fully paid for copy, would MS have the market share they have today. So it seems to me at least that MS has had a piracy problem from the get go... and it didn't really hurt them in the least. 2: His parting line in the letter: "Nothing would please me more than being able to hire ten programmers and deluge the hobby market with good software ". I just have to laugh when I read that. Well, he got the deluge part right. :-) (Disclaimer: Yes, that is a clear MS bash statement, but it is tongue in cheek... yes, I personally don't care for MS software over many of the alternatives... but in the long run, most of their stuff really isn't THAT bad... its just fun to say it is). -chris <http://www.mythtech.net>

Mac SE/30 accessories availability?

by cb＠mythtech.net

>Oh, and FYI, no >matter what Apple says, if you can track down 8 4meg 32 pin simms >(remember those?) your se30 will happily address 32 megs of RAM. Apple never denied that the SE/30 would address 32 meg of RAM. Its part of the spec. What they denied was that it can address 128 megs of RAM (8 16meg 30 pin chips). That has been reported by many to work just fine. -chris <http://www.mythtech.net>

HP 2100 cpu plea

by jwest＠classiccmp.org

Ok folks, I'm officially desperate. I can't figure out what is wrong with the 2100 IOP cpu memory section on my 2000/Access system. So, just thought I'd post this to the list....forgive my begging, it isn't pretty *Grin* Anyone have a working HP 2100 cpu available? I will pay real $$$ at this point, or trade probably just about anything I have for one. If anyone has one they will sell, or trade for, or give away to a place (me) that will actually use it and not throw it on a shelf, I would like to know. I'd also welcome any leads as to where one might be stored, etc. Or, as an alternative, if anyone has a magical device that will instantly transfer all of Tony Duell's repair knowledge and ability to my brain, that might work ;) FYI - I need either a 2100A or 2100S cpu. Don't need or want any 21MX or 1000 type cpus. Thanks! --- [This E-mail scanned for viruses by Declude Virus]

PET 2001 oddity

by mhstein＠canada.com

Ethan: thanks for the info; I've never seen a dynamic RAM 2001N, although a friend of mine home-brewed a static > dynamic conversion. 4032s of course, but I take it you're talking about a real small-B/W-screen 2001. I sometimes toy with the idea of building a PET using modern chips; shouldn't be too big a deal (very low on my to-do list though). Adrian: Was working on adding my .02 to the discussion, but read on and saw that you're in business. If you can't find any locally, I've got several tubes of 2114s here in frosty Canada. And they are used in pairs because they're only 4 bits wide (x 1K). One of my PETs, with an MTU graphics board, is dead as well; this discussion just might motivate me to have a look at it. Good luck! mike
