Arggh, sorry. I simply copied the link from my page:

  http://www.chiappa.net/~jnc/tech/V6Unix.html  

and didn't check it. :-( I'm a bit suprised that Warren broke everyone's deep
links by re-organizing...

Argh. I thought there _used_ to be disk images there - maybe they got removed?
Anyway, the one you want is now here:

  http://ana-3.lcs.mit.edu/~jnc/tech/unix/V6Root

Just decant all the bits onto a RK pack, starting at block 0, and you should
be able to boot that pack.

(I'll fix my page a little later, burned out after the microcode
transcription!)

It's just a plain copy of the contents of a V6 distribution tape. IIRC, SIMH
wants 'tape' files with meta-data such as the length of each tape record, file
marks, etc.
