[TUHS] 1bsd compatible ar utility

Hi All,

I am working through a 1BSD installation on Research Unix V6. 
The||cont.a archives use magic |0177545|, which stock V6 ar does not 
understand. V7 appears to be able to, but on V6 it immediately dies with 
|Bad system call|. Inspection shows references to later calls including 
|access|and |ioctl|, so it appears to have been linked against a post-V6 
libc. I came across some old emails talking about this and an nar 
utility... Does anyone know where the source for this |nar|utility 
lives, or of a V6-native |ar|that supports |0177545|archives?

newoldar on the host works fine, too, but I'd rather not extract on the 
host. I'm hoping to do this native. I'm working with a pristine v6 
installed from tape on pdp 11/70 with split I/D and FPP (opensimh).

1BSD doesn't include an ar utility in the tarball on TUHS. Did folks not 
do this from pure v6? or what?

Thanks,

Will
