[comp.sys.apollo] Sun Tar Tapes on Apollos

I know I've heard this discussed out here before, but I
never thought it would happen to me!

How can I read a Sun Tar tape written with /dev/rst0 on
an Apollo node ?  My local SE says it can't be done with
the device (rst0) chosen by the Sun user that wrote the
tape.

Using tar tf /dev/rct8 gives "blocksize = 0" .

Don't tell me to make friends with our Sun administrators.

I believe the Sun's G

(let's start this again)

I believe the Suns have two device files,
/dev/rst0 and /dev/rst8. The rst0 file writes
the old QIC-11 format tapes (which are lower
density) and the rst8 device writes the
newer QIC-24 format. The Apollo cartridge 
drives handle QIC-24 tapes only.

From what I remember reading here before and trying, you have to
use /dev/rst8 on the Sun since the Apollo cartridge drives cannot
read the lower density /dev/rst0 format.
