Glad it's working. We probably need to create Joy's tarball in the future
with the same file ordering he used and get that the Warren. The trick is
getting a v6tar that properly works. Maybe one thing we should do is
write a tp format 'tape' with the v6tar binary on it and get that in the
archives independently.
When V7 came out, there was a way to create v6tar (which I suspect is
somehow part of Joy's image). The issue is that some of the system calls
changed in small but important ways. tar was a much better way to move
files around than tp which is why it so quickly became the archive scheme
in the Unix community.

After much travail, I found a post in some ancient

translate, but just did the enblock:
gunzip -d 2bsd.tar.gz
cat 2bsd.tar | enblock > 2bsd.tap
I attached the result, et voila:
tar xv0
tar: bin/ - cannot create
x bin/csh, 40412 bytes, 79 tape blocks
tar: bin/etc/ - cannot create
x bin/etc/htmp, 0 bytes, 0 tape blocks
x bin/etc/install, 81 bytes, 1 tape blocks
The cannot create messages are filthy lies :).
That brought it all back to me - just like when I built tar from tape
for v6... sheesh, why does it have to be so painfully difficult to
remember these tricky bits?!
Anyhow, afterward, I went back, did the translation from Japanese to
English (or google did), and it was good stuff about how to apply
2bsd.tar to v6:

Thanks for the help and patience.
