New Version of Apout PDP-11 Emulator

Welcome back to all the PUPS mailing list members! They've finally turned our router back on here, so now the list server Minnie is no longer deaf. Over the past few weeks I've been working on my Apout simulator, with help from Tim Shoppa, and it now runs binaries from 1st Edition UNIX. The announcement is below; details of how to obtain the source, and some UNIX binaries, are also given. Hope you all had a good festive break, and best wishes for the New Year. Cheers, Warren Apout -- Simulate PDP-11 Unix a.out binaries Version 2.3 Alpha Warren Toomey wkt(a)cs.adfa.edu.au January 2000 Introduction ------------ This program is a user-level simulator for UNIX a.out binaries. Binaries for V1, V5, V6, V7, 2.9BSD and 2.11BSD can be run with this simulator. The user-mode PDP-11 instructions are simulated, and TRAP instructions are emulated by calling equivalent native-mode system calls. The advantages of an a.out simulator over a full-blown PDP-11 simulator are: + system calls can be done natively, thus speeding up execution + the simulator is less of a CPU-hog than a full-blown PDP-11 simulator + you don't need a simulated operating system or a simulated file system Apout can be obtained via anonymous ftp at minnie.cs.adfa.edu.au in the directory pub/PDP-11/Sims/Apout. The directory pub/PDP-11/Sims/Apout/UnixBins contains tar archives of a.out binaries from several versions of UNIX. Status ------ The program is now at release 2.3 Alpha1. Most of the binaries from V5, V6 and V7 run fine. All of the V5/V6/V7 system calls are caught, but some are ignored and some generate EPERM errors. The V1, 2.9BSD and 2.11BSD environments are still under construction: see the file LIMITATIONS for details. Finally, the simulator won't run on a big-endian machine.

Read on..... ----- Forwarded message from Keith Bostic ----- Hi, Warren, I'm digging out some old email, and found the following: I think I'm just the one that checked it in... around that time I went through the source tree and committed everything into SCCS, and, my bet is that those files weren't already under SCCS. I also broke the single calendar file up into a bunch of different files as part of re-writing calendar(1) to make it AT&T free. You might want to look in early releases for a "calendar" source file, and not "calendar.computer" (although I'm not positive it was named "calendar", I'm pretty sure that I broke an original file up into multiple files, so I created the "calendar.computer" file and filled it with stuff from an already existing file). Not me. Did you ever figure out where the line came from? --keith ----- End of forwarded message from Keith Bostic ----- Received: (from major@localhost) by minnie.cs.adfa.edu.au (8.9.3/8.9.3) id MAA29790 for pups-liszt; Tue, 4 Jan 2000 12:15:39 +1100 (EST) Received: from henry.cs.adfa.edu.au (henry.cs.adfa.edu.au [131.236.21.158]) by minnie.cs.adfa.edu.au (8.9.3/8.9.3) with ESMTP id MAA29784 for <pups(a)minnie.cs.adfa.edu.au>au>; Tue, 4 Jan 2000 12:15:19 +1100 (EST) Received: (from wkt@localhost) by henry.cs.adfa.edu.au (8.9.2/8.9.3) id MAA04392 for pups(a)minnie.cs.adfa.edu.au; Tue, 4 Jan 2000 12:40:19 +1100 (EST) From: Warren Toomey <wkt(a)cs.adfa.edu.au> Message-Id: <200001040140.MAA04392(a)henry.cs.adfa.edu.au> Subject: 200 Ancient UNIX Licenses To: pups(a)minnie.cs.adfa.edu.au (Unix Heritage Society) Date: Tue, 4 Jan 2000 12:40:19 +1100 (EST) Reply-To: wkt(a)cs.adfa.edu.au X-Mailer: ELM [version 2.4ME+ PL43 (25)] MIME-Version: 1.0 Content-Type: text/plain; charset=US-ASCII Content-Transfer-Encoding: 7bit Sender: owner-pups(a)minnie.cs.adfa.edu.au Precedence: bulk Hi all, Just a note to say that I have received SCO Ancient UNIX licenses up to AU-201 in the mail today. Another note: a bug in the date libraries in 5th and 6th Edition Unix prevents ctime() from properly displaying dates after November 1999. I haven't bothered to find/fix it yet.
