Building a tape IMAGE of Fred's Ultrix-11 3.1

by Madcrow Maxwell

I downloaded the tape building kit of Fred's enhanced Ultrix 3.1 and set about trying to build an image file suitable for use with SIMH. As simply modifying the included script to write to a normal file instead of a (non-existant) tape device failed, I tried doing things by hand, running maketape and then "cat"ing the file it created along with all the other files "dd"ed by the script into a single file. While this produced a file that looked about the right size, it didn't work with SIMH as mounting it to the emulated TK50 device and booting produced: HALT instruction, PC: 016300 (CLR R3) Any help on how to get a working image available so that my nerdy history project can proceed?

Does anyone know if those games available on simh's site called "Adventure" and "Dungeon" will run on the V7 ? Bill

You need to put file marks between everything logically 'dd'-ed In the .tap format, file marks are four bytes of 0. End of tape should have two sets of file marks (eight bytes of 0) FWIW, I sent warren a .tap image of Ultrix 2.0. Never heard anything from him about it.

Porting UNIX...

by Bill Cunningham

Actually what I meant Gregg was Jon Pertwee was the Doctor back in the '60s which is the time period you were referring to, and Troughton too I guess. That reminds me of an episode called "The time..." something or other with Roger Delgado. They were trying to do something with some type of computer obviously an old mini of some type and some anciet artifact. There were toggle switches and lights. Otherwise it certainly didn't look like and PDP that I've ever seen in pictures. Just to get close to one of those old things would be breathtaking. Before my time though. Bill

Porting UNIX from a DEC PDP-11 family member to a DG (Data General) Eclipse family member

by Gregg C Levine

Hello! I have here a Doctor Who book which takes place during the early part of the computer revolution, about the time the whole of what's discussed here happened. The people concerned in the book have machines running UNIX. Some of these are indeed PDP-11s and there are also a few DG Eclipses. Now the question: How difficult would it to port UNIX V7 from the usual machine, probably a PDP-11/43 (But I might be wrong about the model!) to a DG Eclipse? Naturally since I don't have physical hardware here, the intended target would be a SIMH DG virtual Eclipse (Or even a Nova 4) and the one doing all the work would be a SIMH PDP-11. -- Gregg C Levine hansolofalcon(a)worldnet.att.net "The Force will be with you.

These two lines are only meant as templates to replace some files in your archives, that is lib[12], if necessary. But replacing an object file is necessary only if you changed the corresponding source file and recompiled it. Here are the files supposed to be in lib1: # ar t lib1 main.o alloc.o iget.o prf.o rdwri.o slp.o subr.o text.o trap.o sig.o sysent.o clock.o fio.o malloc.o nami.o pipe.o sys1.o sys2.o sys3.o sys4.o > >I have these missing symbols ># ld -x l.o m40.o c.o ../lib1 ../lib2 >Undefined: >_end (defined by ld if successful) >_edata (same) >_iinit (from alloc.c) >_iget (from iget.c) replace lib1 and lib2 with the original files and it should work! You might want to consult http://www.ba-stuttgart.de/~helbig/os/script/chapt1.1 for help installing V6. Regards, Wolfgang -- "Dijkstra is right, but you don't say such things!"

[pups] V6 kernel compile help

by filter

Hi All I need help with the V6 kernel compilation. I read the Unix setup guide and the file /usr/sys/run. I've seen one problem so far with the /usr/sys/run file. That is that the two lib files (lib1 & lib2) did not contain any symbols. When I ran: # ar r ../lib1 and # ar r ../lib2 I got a string of error messages from ld. But after I did this: # ar r ../lib1 *.o and # ar r ../lib2 *.o I have these missing symbols # ld -x l.o m40.o c.o ../lib1 ../lib2 Undefined: _end _edata _iinit _iget _update _schar _namei _maknode _access _itrunc _iput _alloc _uchar _closef _getf Can anyone help me with this? (I saw that MIT athena has a V6 repository with a Makefile in it But I cannot access it at all. (-_-) ) thanks bent lee

Re: [TUHS] weird problem with our Decwriter III terminal

by John Chung

I would start with the gears first. Stepper motor testing can be done by visual inpection by running through 1 character at a time. Mark each turn when moving to the next character. This requires diassembly of the casing and other visual blocking components.

weird problem with our Decwriter III terminal ...

by asbesto

Hi, maybe someone here can help us - our problem is that the decwriter terminal seem to "jump" in particular positions when printing we don't understand how to solve this problem - maybe this is a stepper motor problem, or another problem in gears/transmission? the problem is evident in this image: http://dyne.org/museum/dec/terminals/la120/tn/dscn3488.jpg.html does someone have an idea about this problem? tnx! :) -- [ asbesto : IW9HGS : freaknet medialab : radiocybernet : poetry ] [ http://freaknet.org/asbesto http://papuasia.org/radiocybernet ] [ NON SCRIVERMI USANDO LETTERE ACCENTATE, NON MANDARMI ALLEGATI ] [ *I DELETE* EMAIL > 100K, ATTACHMENTS, HTML, M$-WORD DOC, SPAM ]
