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

Ken, if you send it to my personal email account, there's no size
restriction (I run the mail server); it's iking at killthewabbit.org. I would
greatly appreciate your sending it to me. BTW, I've been using 1977 (the
year I graduated fron high school) on my PDP-11 under RSX-11; some tools
won't accept the "01" year. :-)
Cheers -- isk
PS: I've hired a lot of Waterloo folks -- smart buggers, the lot of them.

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^)
