Yea, I had figured that out after I posted. I used:
dd if=/dev/rrx2 of=/tmp/rt11.n bs=256
Wouldn't ya know after I created a new tape on the 11, I go to read it
on my PC and my SCSI 9-track tape drive has died. It won't power up.
:-( I smelled something funny in my office when I got home today but
couldn't quite figure it out (the drive was "on" but in standby). I
guess I know what that smell was.
Go figure. A tape drive that is > 20 years old works great. A newer
one (what are the dates on a TSZ07?) dies. I guess the old adage "They
don't make 'em like they used to" still holds.

That's how I got the original RL02 image onto the 11/45. I like tapes
because then I don't have to move equipment around (and it's quite a bit
faster than 9600bps over a serial line).
