From rnordier at nordier.com Fri Oct 5 03:51:05 2007 From: rnordier at nordier.com (Robert Nordier) Date: Thu, 4 Oct 2007 19:51:05 +0200 Subject: [TUHS] New V7 port available Message-ID: <20071004175105.GA48428@nordier.com> A new port of UNIX Version 7 to the x86 (IA-32) based PC is now available. The port, called V7/x86, was originally done around 1999: "as something to do with the UNIX source code", when the $100 source licences first became available. Over the last year or so, I've been working intermittently at preparing it for release. In classic porting style, the port includes a 16- and 32-bit UNIX-style x86 assembler written from scratch, though the next step of conjuring pcc to emit 32-bit x86 code was not done. Originally, the system used the TenDRA C compiler, but TenDRA is huge and this was never a good match. (Without demand paging, and with restrictions on the size of the buffer cache, there is a definite limit to how big you want much-used binaries to be.) However, since the Amsterdam Compiler Kit was released as open source, the ACK K&R compiler, with a backend revised to speak "as" rather than "ACK assembler", works very well. V7/x86 currently supports ATA (IDE) hard drives, ATAPI CD drives, a 1.44M floppy drive, and standard serial ports, in addition to the usual PC screen and keyboard. For easier installation and setup, supplied utilities allow access to CD (ISO 9660) and FAT (MS-DOS) filesystems. Boot code uses the PC BIOS. At present, there is no SCSI support. Overall, the system is stable and quite generally usable. For instance, it is an easy-ish task to build the V7/x86 distribution on V7 itself, including packaging it as a small CDROM image. When using the C shell, together with contemporary versions of vi and more, one even tends to forget this is V7. (Given the absence of X and TCP/IP, the overall "feel" of the system is something like an early SCO System V release: though possibly not so unreliable.) The port was originally done more for the sheer pleasure of getting to grips with the V7 source code than for any good reason. But I've since spent a bit of effort trying to put together a fairly usable release -- though there will be plenty of rough edges -- in the hope that, for instance, some school or college might eventually take the thing up as a vehicle for students to get practical experience on. After all, it really is possible to write (say) a device driver from scratch and get it working in the course of only one or two evenings. Of course, the PDP-11 original can be (and I hope still is) used for that purpose, but presumably PC architecture, and devices, and assembly language, would all be part of a modern curriculum, anyway, leaving fewer layers of obscurity for the student. Anyway, if any of you would like to take a look at the thing (even if only to point out some of the more egregious of the remaining errors) the link is http://www.nordier.com/v7x86/ Apart from actually installing the system on some suitable PC, it is also possible to boot from the CDROM or floppy image and then simply quit out of the install utility to the shell prompt. Alternatively, the system can be fairly readily run under Bochs or some other emulator, using the available "demo" image. There is a short user-oriented introductory document, with examples, here http://www.nordier.com/v7x86/doc/v7x86intro.pdf What is presently lacking is a document containing a more technical description of the port, but I hope this will be available before too long. As far as the web pages are concerned, these were originally set up before the 10 August 2007 Judge Kimball ruling in favour of Novell. No changes have been made (to copyright notices, licence information, etc.) in the light of that ruling, though of course I will willingly make changes if and when I know what they should be. Incidentally, there's been mention, here, in the past, of one or two projects to port V7 or 32V to the PC. For all I know, these may still be ongoing: V7/x86 is an unrelated effort. -- Robert Nordier //////////////////////////////////////////////////////////////////////////// Nordier & Associates rnordier at nordier.com Telephone: +27 31 261-4895 PO Box 11266, Marine Parade, 4056, South Africa Mobile : +27 72 265-2390 //////////////////////////////////////////////////////////////////////////// From jkunz at unixag-kl.fh-kl.de Fri Oct 5 04:10:17 2007 From: jkunz at unixag-kl.fh-kl.de (Jochen Kunz) Date: Thu, 4 Oct 2007 20:10:17 +0200 Subject: [TUHS] New V7 port available In-Reply-To: <20071004175105.GA48428@nordier.com> References: <20071004175105.GA48428@nordier.com> Message-ID: <20071004201017.6fc311a6@SirToby.dinner41.local> On Thu, 4 Oct 2007 19:51:05 +0200 Robert Nordier wrote: > In classic porting style, the port includes a 16- and 32-bit > UNIX-style x86 assembler written from scratch, though the next step > of conjuring pcc to emit 32-bit x86 code was not done.

I have a boot and memory disk driver working, but haven't started the real device drivers working yet. For what it's worth, I started the project with a port of the ACK compiler. It may be useful. You can find it at ftp://opensourcedepot.com/minix/cross/minix-cross-0.1.tar.gz. There also some of my early work at ftp://opensourcedepot.com/32V. I did get a chance to play with v7/x86 in Bochs.

No offense intended, but why waste time on 386 (or even way more time on 286)? I can't imagine that anyone has any of those machines anymore. And if anyone is so broke that they do and can't afford a newer machine I have piles of celeron boxes looking for a home. 300-500mhz with 64-128M and probably a broken disk but maybe it works. You pay shipping and they are yours. If you are doing interesting work and you are really broke I'll pay shipping. But 286? Come on. Let it go, it sucked.

Coherent was a v6 port. There was a Dec Rainbow port as well, but nobody seems to have a copy of that anymore. The only copies I've been able to find are for either the 286 or 8086. The 286 version was a v7 port, iirc.

The 486 has some useful cache instructions like "invd" and "invlpg", but it was the lack of builtin floating point I was thinking of.

Jason I don't mean to cause rain on your parade here, but we've practically beaten the idea behind running the 4BSD series via VAX (emulation) numerous times.

Yesterday I connected again to QNX.com (as I usually do every two or three months) to see whether there was any new release when I found out that it is now released with a "mixed" license, being free for academic and non-commercial use, and -here's the interesting bit- it now includes the full source code to the operating system (microkernel, real time, SMP support, etc...) and comes with a perpetual license (for academic, non-commercial use). You can download the full sources, recompile and modify it and browse the subversion repository online. It has some restrictions of course. It's great as QNX is one of the traditional non-ATT derived UNIX and has been considered the best Real Time operating system for ages. So, while it may not be possible to include the sources in TUHS yet, at least it might be worth having some links on the TUHS site to Sun's Opensolaris and QNX sites so people may know where to get the sources for them. It may seem 'moot' from a 'heritage' point of view now, but it may pay off later if some one keeps private copies of these sources for the record. Who knows how long will the current trend last? And may be we can contact them and ask for permission to include a copy of the tree on the archive (they leave the door open to that) just for historical purposes (with all due disclaimers and acknowledgements).

I have snapshots of our RCS pool back into 1984 or so; unfortunately, I did not copy the RCS pool itself which would have every commit. I also have copies of the X Consortium backups; in there are ClearCase databases which the RCS pool was imported into, and may have the commit by commit history back to the beginning for many files; but it will take someone with ClearCase expertise to retrieve things from that. I've been meaning to do something with these for the last couple years, but have been too busy with OLPC to follow up.

I remember a very old SONY cd-rom reader capable of reading very damaged cd! It was the SONY CDU-33A, it has his own controller, so was not an IDE or SCSI drive. But it can be connected to an old soundcard like Spectrum or other similars, having some cdrom interfaces. sorry for my bad english :) -- [ 73 de IW9HGS : freaknet medialab : radiocybernet : poetry hacklab] [ 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 and SPAM ]
