Installing v7 on SIMH

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 "/PDP-11/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:

are just to tell you what to do when there is ambiguity; please do not type them in literally!

Tape Install

tapei.ini

set cpu 11/45
set cpu idle
set rp0 rp06
att rp0 rp06-0.disk
att tm0 v7.tap
boot tm0

with the config in hand, then let's install.

installation

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.
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 seems to get confused, and echo's everything back in uppercase, however all command are entered in lowercase.

Tape boot

Sadly the rp06 doesn't seem to want to boot... I'll have to troubleshoot it more later, but for now I just boot from the tape, and execute the kernel from the hard disk.

tboot.ini

echo
echo at the prompt type in
echo @ hp(0,0)unix
echo
set cpu 11/70
set cpu 2M
set cpu idle
set rp0 rp06
att rp0 rp06-0.disk
att tm0 xx.tap
boot tm0

And let's boot up!

c:\temp\v7>pdp11.exe tboot.ini

at the prompt type in
