Recover SCO UNIX root password

["Mandelcorn, Seymour" <smandelcorn () bgr umd edu>]

I am trying to recover or reset the root password from a SCO Unix setup. I
have the system but I do not have the startup disks. I tried booting from
Slackware but was unable to mount the partition. I think the filesystem type
is vxfs. Any advice?
