I do indeed remember those manuals - those sturdy binders which let you know these systems meant business. There were never enough of the binders available in the IBM PC dealership I worked in. And lest we forget: the infamous "This page intentionally left blank" page. What's up with that?? I do also memember Wordstar and it's arcane command sequences. Those commands persisted though, through a number of ordinary text editors for programmers & such. Speaking of infantile and utterly bizarre, does anyone remember that abysmal IBM attempt at a word processor, the name of which escapes me at the moment. I think it was vaguely based on their mainframe product, typical of IBM at the time. It's command set was last seen wandering about in their "e" editor in PC DOS 6.xx. It's an amazingly powerful editor in a lot of ways, loads of options and features if you can figure them out. But I'll be danged if I can get the thing to insert a new line... Cheers, Dennis

Still more adventures in PDP-8/L repair

by charlesmorris＠direcway.com

I gave up (for the moment) trying to find the problem with the memory on my 8/L. It never returns anything but all-0's to the MB, but all the control pulses and timing are correct. To make matters worse, while scoping the output of the bit 5 sense amp I discovered it would change every time when I changed bit 0 of the switch register and hit DEP! Meanwhile I decided to go after another problem (when you hit START at 0000 it runs up to 0100 and "hangs" with the BREAK and RUN lights on.) If it's executing 0000's (AND instructions) it should just keep running. The only way to wake it back up is to flip the SING STEP switch (which is NOT how it's supposed to work; LOAD, EXAM, etc. should also clear the RUN flip flop). And nothing was requesting a data break, either! So after some scoping and extender card work, I found the backplane wire from the BRK SYNC flip flop was broken in two. This made for a continuous break request. I fixed it, now it starts and stops like it's supposed to,... And then I looked closely at the backplane and saw three more broken wires! All of them are crossing the gap between the AB row of sockets and the CD row. Guess 33 years of flexing and vibration did them in. They are buried too deep to be mouse bites (besides, the nest was in the back on the module side). Unfortunately I ran out of wirewrap wire and the wife rang the dinner bell. We'll see what ELSE is screwed up next week! -Charles

(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.

VME CPU's: Documentation

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>

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.

Apple Macintosh- where would this be useful?

by kendonchatz＠yahoo.com

I have a 13 year old apple macintosh that works like a dream. It's loaded with programs, and this great little machine got me through law school and helped me launch my career. When my employer switched over to a compaq system, I could no longer use this machine to work on projects at home and was forced to pick up an etower package instead. For the last 5 years, it's sat in my basement waiting. Everything works perfectly, including the printer, and all of the parts are original. Any tips on where I might take this machine so that it can be used? It's a shame to let it sit here and rot.

OT: Crazy C Problem

by jss＠subatomix.com

I'm testing the code I've written to spamproof the ClassicCmp web site and archives. I call the system SpamCamo. The file filter works great and produces links as it should. The CGI program is not behaving and is giving me some *very* wierd behavior. I'm stumped. First, if I compile with this: $ cc -o spamcamo.cgi cgi.c spamcamo.cgi.c -lcipher I get a "Bus error (core dumped)" exception from the first statement in my program, which is printf("DEBUG: 0\n"). I have used gdb to verify this, and it tells me that SIGBUS is occuring inside isatty() in libc. Now, if I compile like this, switching the order of the source files but making NO changes to the source files themselves: $ cc -o spamcamo.cgi spamcamo.cgi.c cgi.c -lcipher The program proceeds to the first call of strdup(), which returns NULL and sets errno to EINVAL. strdup() is definitely receiving a valid string. Furthermore, malloc(1) (as in "allocate one byte") in the same place also fails with EINVAL. The machine is not low on memory. Even furthermore, the code that is failing in this case (in cgi.c) works correctly when compiled against a test program (proof: http://www.subatomix.com/test_cgi.cgi?a=b) instead of spamcamo.cgi.c. This is what the program does (i.e. not much) before calling strdup(): printf() function call function call getenv() return strcmp() funcion call getenv() return strdup() <--- SIGBUS occurs here I get the same results on two FreeBSD boxen. One is running 4.5-RELEASE and the other is running 4.6-STABLE. I'd like to think this is something I've done wrong and not a bug in libc. Any ideas? -- Jeffrey Sharp

"Pete's own undocumented image format" is probably not a good idea :-) Other than that anything that has some supporting documentation available would seem sensible - it'll always be possible to convert between formats then. I get lost trying to remember all the issues regarding writing to discs in different machines (wish there was a website that collected all that information together, for various platforms) - I can't for the life of me remember if it's possible to write to beeb discs with a PC, which would probably be my preferred option. My BBC Master can emulate an XT so maybe there's something on that side that can take a PC format 5.25 disc and write out to a beeb disc. I have no idea... I'm more concerned about the disc set being archived somewhere than delving in and playing around with my ARM unit now though - same goes for other systems. I've already got machines that are non-runners at present because the software has gone and is unobtainable :-( > so 50 or 100 seem likely > numbers for the quantity of ARM Development Kits made to fit Beebs. hmm, mine was pretty late then if they did only make 50. Mine came from Kent uni; I have no idea what it was doing there, but the same place sourced quite a few bits of beeb equipment. Maybe they did some official product testing or something. cheers Jules __________________________________________________ Do You Yahoo!?

INRE: XT Motherboard

by A.Gabston-Howell＠EnigmaOne.com

I *can't* believe I'm actually doing this.....I'm in a situation wherein I need the MB, if you still have it. How's it outfitted? uP and memory, is what I'm thinking of; and does it have the standard 8-expansion slot count? If you still have it, please do let me know, and I'll get back with you quickly. Unfortunately, time is pushing me in this situation. Also, if you *happen* to have a CGA video adapter with at least RGB DB-9 output, composite out (RCA) would be cool, but not necessary. I'd like to get ahold of it at the same time. -- Allan Gabston-Howell "Be wary of any school of thought whose very name is an oxymoron.
