I've assembled some notes from old manuals and other sources on the formats used for on-disk file systems through the Seventh Edition: http://www.cita.utoronto.ca/~norman/old-unix/old-fs.html Additional notes, comments on style, and whatnot are welcome. (It may be sensible to send anything in the last two categories directly to me, rather than to the whole list.)

Help about Data General ECLIPSE MV/7800XP

by asbesto

Hi, here we are back from pdp-11/34 restoration. We haven't installed unix, because we have to prepare a special disk image for V6 to be installed on the RL02 disk (only 10 megabytes :)... now we're working on the Data General we have at our lab in Palazzolo Acreide, a little town in Sicilia (http://poetry.freaknet.org) We had an hardware problem some time ago - the tape had some electrolytic condensers to be changed, the fuse blow out, ecc. ecc., but now we think the main electric part is OK, because the tape start, and try to load the tape ... but using CLI to boot the tape, we have this error: SCP-CLI> boot Boot from what device? [24]: 22 Fatal System Error: Data Channel Bus Timeout AC0 AC1 AC2 AC3 PC CARRY ATU 00000000044 00000200000 00000170360 37700000000 00000000000 0 OFF SCP-CLI> can someone help? We have original DG/UX tapes here, and we want to install them on our disk, that now contain a weird AOS/VS installation (and we have some backup of it in other tapes) sorry for spamming the mailing list - but this list is our only resort :) (and i apologize for my bad, "italian way" english language :))) -- [ 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 ]

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

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
