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.
