CCI (Power 6/32*) HELP NEEDED (corrupt passwd file)

[The Daily Dross]

Hello Networld,
stupid me managed to scramble the /etc/passwd file on a CCI
(Power 6/32S) System 5 computer (tried to put /bin/csh in
root entry of /etc/passwd and Sys5 doesn't like it).
Never finishes startup, because init loopes with:no shell.
Can't find the darned root-tape!!
Who can lend us a copy (with in /etc/passwd only root entry) or
knows how to solve this problem?
PLEASE HELP FAST!
