[pups] A bootable disk image for a PDP-11/34?

[Ken Wellsch]

Hi Ian,

Indeed, looks like there has been some bit rot on the archive... sigh.

Luckily I am a pack rat and have copies of my Waterloo days data.  The
images are all clean there.  Curiously enough I even found the directory
where I ran that simulation (circa Oct/94 I see).  I just rebuilt the
code there and ran it on my NetBSD/i386 system and it boots V6 just fine.

In case you don't read minds, after doing the 'attach ...' then 'boot rk0'
the intuitive V6 boot prompt '@' is where you type 'rkunix' for example B^)

Almost instantly I had a 'login:' prompt, and the image is off the tape
so there is no root password set...

Don't forget to type 'date' when logged in ... it is a hoot to see B^)

Oh heck, never thought to actually try to set the date, post 2000...
maybe better to let it live back in 1975...

I've tar/gzip'ed the bundle.  Do you want me to try and UUencode it
and mail it to you?  It is nearly 1 Mbyte in binary form...

Oh yeah, as Warren mentioned, stock V6 does not run on a '34.  I think
it ran on a '40.  I know it can run on a '34 because in 1980 I started
using UNIX, V6 running on a '34  B^)

Cheers,

-- Ken
