I figured it out - on Keith Bostic's v7, using the default makefile for v6tar: make v6tar cc -O -c tar.c cc -c -O /usr/src/libc/v6/access.c cc -c -O /usr/src/libc/v6/chown.c cc -c -O /usr/src/libc/v6/execl.c cc -c -O /usr/src/libc/v6/ftime.c cc -c -O /usr/src/libc/v6/gtty.c cc -c -O /usr/src/libc/v6/lseek.c cc -c -O /usr/src/libc/v6/stat.c cc -c -O /usr/src/libc/v6/syscall.s cc -c -O /usr/src/libc/v6/time.s cc -i -s -O *.o -o v6tar # dd if=v6tar bs=128 count=1|od 000 000411 037100 004224 027466 00 00 00 01 ... man cc says -i and -s are passed through to linker, so man ld says -i creates separate I+D and -s strips symbol table. I compiled the binary without these (I thought I would keep the symbol table as an excercise) using: cc -O *.o -o v6tar The resulting binary is 407, yay!: dd if=v6tar bs=128 count=1|od 000 000407 037040 004224 027466 020744 00 00 01 ... I copied it over to v6, lo and behold, it works on a PDP11/40 without separate I+D! Thanks, Will ___ Simh mailing list Simh@trailing-edge.com http://mailman.trailing-edge.com/mailman/listinfo/simh
Re: [Simh] Graphics Terminals and Graphic System Phototypesetters
Will The quick answer is yes. Check out vtroff on the BSD tapes. The Versatec plotter was used to simulate a C/A/T typesetter which is what the original troff created and before the laser printer was in common use.

I usually do this by just tar'ing to/from a disk file, something like: on pdp11: tar cf /dev/rxp0c myfiles on host: tar xf simh-disk-file Works both ways :-) -- Ragge Hi, This sounded promising, but as it turns out there appear to be 2 problems... 1. v6 doesn't have tar, and 2. it looks like v6 doesn't have rx device support (floppies). Are you using v6 with tweaks, or v7, or some other variant of unix? Hm, it was some time ago, but I think it was tar. Otherwise try cpio? You do not have to use floppies. rxp is the raw device for rp disks (avoids caching). Just work against that file. To close the loop on this, I have been able to follow the closing advice in "Setting up Unix - Seventh Edition" and use its v6tar on v6. It appears to require split I+D, so I had to "upgrade" from the 11/40 to an 11/45 or 11/70 (both work). It requires the the kernel be recompiled with separate I+D support with m45.s and such, but pretty straightforward. I haven't done a lot of copying yet, but at least I am able to share between v6 and v7. I have also worked out a couple of different ways to move files to and from the host that involve the disk or tape. I wrote a perl script to read a SimH tape into its constituent files that works ok as a way to transfer files as well (clunkier than tar and such, but it was a good learning exercise).

[Simh] Graphics Terminals and Graphic System Phototypesetters
All, I am using the SimH PDP 11 simulator to learn about the PDP 11/40/45/70 architectures with a particular focus on Sixth and Seventh Edition Unix. I have written a couple of notes based on my experiences/trials that are available at: v6 - http://decuser.blogspot.com/2015/11/installing-and-using-research-unix.html and v7 - http://decuser.blogspot.com/2015/12/installing-and-using-research-unix.html I am open to comments, suggestions, and criticisms, I have been getting an inordinate amount of help from the folks on the TUHS mailing list with respect to the Unix side of things, but now I am looking into the SimH side of things and was hoping y'all might help... Is is possible to simulate a graphics terminal in SimH for the PDP-11/40/45/70. So far, I have been able to get a text console working (I think it's a Teletype ASR-33) and serial consoles (DCI). I have seen some video of real PDP's playing lunar lander and such on graphics terminals, and if this is possible in a simulated environment, I would like to try it out. Also, is it possible to simulate a graphics system phototypesetter? I get the feeling that this is what TROFF was actually designed for and would be interested in trying it out, as well. I'm a relative newbie to SimH, PDP 11's, and Unix v6/v7, so if I'm completely off base in my questions, please let me know.
