Hmm:
dd if=/dev/rrk0 of=ucbtar bs=1b
no space on dev 6/0
write: No space left on device
1175+0 records in
1175+0 records out

ls -l
-rw-rw-r-- 1 root   601088 Dec 31 19:41 ucbtar

df
bad free count, b=1
/dev/rp0 0

yeah, well no kidding, that file is WAY bigger than the file on the 
host. so...

rm ucbtar  (or bad things WILL happen with no space left)

set bs explicitly on the mac side of things
dd if=tar of=ucbtar bs=512 conv=sync
27+1 records in
28+0 records out

ls -l
-rwxr-x---  1 wsenn  staff      14156 Jul 27 22:32 tar
-rw-r--r--  1 wsenn  staff      14336 Jul 27 22:44 ucbtar

so back in v7:

set bs explicity  and # blocks to read (otherwise it reads past the size 
of the file, simh quirk?)
dd if=/dev/rrk0 of=ucbtar bs=512 count=28
28+0 records in
28+0 records out

# chmod 0755 ucbtar
# ls -l
total 28
-rwxr-xr-x 1 root    14336 Dec 31 19:47 ucbtar

# ./ucbtar x

directory checksum error
echo $?

Haha, I'm learning, but I wanna cry :).
