Revision as of 22:52, 4 November 2017
This is the procedure I'm using to install Research Unix v7 on SIMH's PDP-11 emulator.
I'm using the files from TUHS "/Archive/Distributions/Research/Keith_Bostic_v7/" directory. I've also uploaded the resulting tape to here.
If you are going to build the tape then you'll need the mkdisttap.pl script to output a v7.tap file.
NOTE: Comments at the end of a line of the form:
[## Comment]
are just to tell you what to do when there is ambiguity; please do not type them in literally!
Tape Install
tapei.ini
cat > tapei.ini <<EOF set cpu 11/45 set cpu idle set rp0 rp06 att rp0 rp06-0.disk att tm0 v7.tap boot tm0 EOF boot tm0
with the config in hand, then let's install.
installation
pdp11 tapei.ini PDP-11 simulator V3.8-1 Disabling XQ RP: creating new file Overwrite last track? [N] [## Just hit enter] Boot :
I just hit enter to the "Overwrite last track" question, then the bootloader will appear. We are going to load the 3rd program on the tape, mkfs and format the 'a' partition.
Boot : tm(0,3) file sys size: 5000 file system: hp(0,0) isize = 1600 m/n = 3 500 Exit called Boot :
The block size comes out of pre-compiled disk sizes in the kernel. Unix back then wasn't as dynamic as what we like in these modern times...
Boot : tm(0,4) Tape? tm(0,5) Disk? hp(0,0) Last chance before scribbling on disk. [## Just hit enter] End of tape Boot :
Once the formatting is complete, then it'll drop back to the bootloader, and we are going to load the 4th program which is the restore program, and we'll restore the root partition.
Now we can boot up UNIX from the hard disk, and setup the OS. The console driver echoes everything in upper case letters, however all command are entered in lowercase. We'll set stty to lowercase and speed up carriage returns and linefeeds.
Boot : hp(0,0)hptmunix mem = 177344 # STTY -LCASE NL0 CR0 #
Copy the kernel to unix and remove the extra versions.
# mv hptmunix unix # rm hp*ix # rm rp*ix # ls *ix unix #

Normal boot
Create a normal boot ini file for booting directly from the RP06. Note that SIMH will display Disabling XQ and wait for you to type boot to start the actual boot process on the RP06.
nboot.ini
echo echo After Disabling XQ is displayed type boot echo and at the : prompt type hp(0,0)unix echo set cpu 11/70 set cpu 2M set cpu idle set rp0 rp06 att rp0 rp06-0.disk boot rp0
And let's boot up!

The default root password is 'root'.
Additional Information
A longer tutorial describing the installation and configuration process in additional detail is available online here and as a printable PDF here. As of October, 26, 2017, version 1.6 of the tutorial covers the basic installation from tape to disk, booting from the disk, reconfiguring the system, rebuilding the kernel, logging in as root, and as dmr, sending and reading system mail, and enabling the V7 instance and SimH to allow multiple sessions from the host machine to the instance via Telnet.
