I am having problems reading my NCR Tower 1/4 inch
cartridge tapes on other Unix machines (such as
Sun equipment).  I have a Tower 32 with a M68020 and 
2 HPSIO boards (16 ports).  I don't know what format the
tape drive is writing and why doing a tar tvf on a Sun 68020
based workstation won't read this tape.  I have tried 
reading the tape using the quick-24 and quick11 and quick-3 
formats but I always get:

tar: directory checksum error (1 != 5663)

Anyone else had such a problem or know details of the
type of tape drive my NCR might have?  The NCR cannot read
any tapes produced on Sun equipment either so it seems they
are incompatible in both directions.  I Haven't been able
to try other brands of machines yet.

Thanks in advance.
