Helwig,

$ cd /usr/src
$ ls -al
total 2
drwxrwxr-x  2 bin       224 Sep 25  1980 .
drwxr-xr-x 17 root      304 Feb 15 19:30 ..
$

These are the disks I am using

Interdata Unix V7
    iu7_dp0.dsk     10MB disk image containing / and /usr
    iu7_dp1.dsk     10MB disk for swap and /tmp

Both dated 23 Feb, 2003.

If there is a better set let me know. I could not get Unix V7
to run under PDP-11 so I am using Interdata-32.

Thanks
