Apollo-Sun cartridge tape reading thru tar?

[Cynthia G. Anderson]

my problem is two-fold.

question 1: for the apollo folks--

I'm trying to get the tar command to read a cartridge tape of mine.  the
tape was made using wbak and has a single file on it.  to get a listing I
type:   (in c-shell) tar tbf 1 /dev/rct8 what I get is an error " tar:
directory checksum error (0 != 10459) ".  I don't understand exactly what
I'm doing wrong?  any ideas?

question 2: for both apollo and sun people--

I want to be able to write a cartridge tape so that either the a sun-3 or
4 OR an apollo DN 3010 can read it.  I've been told it's possible using
tar and some sort of particular format forced on the tape; but I haven't
found anyone here who really knows how to do it.  help?

thanks so much for any and all suggestions...
