Apple 40SC

[Glenn]

I am also trying to get my tape drive to work under AUX.
I tried the autoconfig suggested  in previous messages and 
now when I boot AUX it claims that 
tc: 40SC tape driver ver 1.9 is loaded
mt -f /dev/rmt/tc1 format
formats the tape fine. (I verified this under MacOS)
Other mt commands such as rew and fsf work fine.
tar, cpio and dd dont work. They all say read or write error.
dd says "write error: no such device or address".
Has anyone any ideas?
