this suggests the PWB/Mashey shell was pretty short lived...

derivatives of Unix Version 7 were about the first Unix version most 
people outside of a few universities ever saw, like I believe my first 
in depth exposure to Unix was 4.1BSD, on Dec VAX 11/780.   I remember 
having to get a Unix/32V license from AT&T, then photocopy the label of 
the tape and fax it to Berkeley before we could get 4.1BSD from them due 
to licensing weirdness.  I don't remember ever even mounting that AT&T tape.
