Weird result about a test on the pdp11/34 ...

by asbesto

Sorry for this, we are here for a 48 hour continued debugging session at Freaknet Medialab, trying to restore this pdp11/34 ... now we discovered this: running a program full of NOP, followed by HALT, it stop after 12 cycles !!! so, if the program start at 1000, and end at 1100 with the HLT istruction ... the CPU STOP showing 1012 !!! and, if we input the program starting from 1400, all NOP, with the HLT at 1500, it stop at 1412! and, sometimes, it stop on address 002002 !!! it seem not executing the HLT ... what can it be ? :( the 128K mos memory M7891 i tried to repair some time ago ? p.s. the program itself is as we wrote in :! if someone can answer in real time, it would be great - we are also on IRC, #pdp11 on ircnet, and ICQ 36294456. :D -- [ asbesto : IW9HGS : freaknet medialab : radiocybernet : poetry ] [ http://freaknet.org/asbesto http://papuasia.org/radiocybernet ] [ http://www.emergelab.org :: NON SCRIVERMI USANDO LE ACCENTATE ] [ *I DELETE* EMAIL > 100K, ATTACHMENTS, HTML, M$-WORD DOC, SPAM ]

Original 9 track tape of Unix 7th edition from Bell Laboratories.

by James Falknor

To all concerned, I discovered this little gem up for auction on E-Bay. One of the stickers state that it is Seventh Edition from Bell Labs I have placed a small bid on it ($5.00 US). Advice required: 1. Would it be worth continuing to bid on? 2. What should my highest bid be? 3. Would TUHS be interested in the tape if I should win it? I don't have a tape machine or computer for such tape. Thank you, James Falknor

Debugging a PDP11/34

by asbesto

Hi, can someone give any hint about debugging a PDP11/34 ? If you remember, we had strange hardware problems and the pdp11/34 can't boot anymore. In these days we will do some testing, so ... we need help! :) tnx all p.s. for info about the problem here: http://groups.google.co.jp/group/alt.sys.pdp11/browse_thread/thread/7b11ffe… -- [ asbesto : IW9HGS : freaknet medialab : radiocybernet : poetry ] [ http://freaknet.org/asbesto http://papuasia.org/radiocybernet ] [ http://www.emergelab.org :: NON SCRIVERMI USANDO LE ACCENTATE ] [ *I DELETE* EMAIL > 100K, ATTACHMENTS, HTML, M$-WORD DOC, SPAM ]

Any Thuth or Zed stuff out there

by Brantley Coile

Are there any people who worked with Thuth or the language Zed out there? Any hope of getting the source for the Zed compiler or a compiler for the Eh language? Brantley

PDP-11/23 plus minicomputer

by James Falknor

To all interested, This is not meant as a advertising. The following is meant for informational purposes only. An entire PDP-11/23 system plus minicomputer is currently up for auction on E-Bay. http://cgi.ebay.com/Digital-Equipment-Corp-PDP-11-23-plus-minicomputer_W0QQ… There is a person that has requested that the disk drive and disks be dumped if that person should win. There are 2 disks marked "system" on them. As a part of The Unix Heritage Society, I believe we need to keep this system intact. I personally do not have the money to successfully bid and win. I hope somebody from The Unix Heritage Society will take up the cause and make a successful winning bid. The system in it's entirety is a part of The Unix Heritage.

IBM Xenix 1.00

by James Falknor

To all concerned, I recently came into possesion of IBM's Xenix 1.00 on 5.25 floppy disks for free. Problem is that it is missing disk 3 of 3 or the 4th disk in the set. I have the Installation disk, Disk 1 of 3, and Disk 2 of 3. Does anybody, by any chance, have the 4th disk, Disk 3 of 3 that they would be willing to share? Or, is that not allowed to be asked here? Thank you, James

Borland's C++ BuilderX, Personal Edition

by James Falknor

To all you programmers, I'm sure you're scoffing at me, but I just obtained Borland's C++ BuilderX, Person Edition. It only cost $10.00 U.S. dollars direct from Borland. I plan to teach myself how to view, modify, replace, and write/re-write Unix Operating System code. May I rely on help from TUHS expert programmers? I know I'm going to need the help. My ultimate goal is to bring Unix Version7 into the 21st century. Since 4.3BSD contributed code into Unix Version8, I feel I will probably use portions of the latest BSD sources that are legally available. Again, if I may use those of you that programmers help, I would surely appreciate it alot. Thank you, James Falknor

As I said I can build everything(using V7 make,cc ans as), it means I can work, and I do not need ANSI terminal (if You have meant true VT100 terminal, and not TERM=vt100 on PC, BTW apout for version 7 assumes as default TERM=vt100 ). I was meaning building in pdp environment running in Coherent, and not building in Coherent via for example a crosscompiler or so.

I have already tested succesfully more_v7 , which I obtained from Tim. Thanks. I will let You know how it works. Andrzej
