This is what is confusing me.  It works fine on the sun3 port when
I put a 3/160 cpu in it, but on the sparc it does not work.  That
was leading me to think there was something slightly different between
the traditional sparc and the sun3 port.  The sun4 is actually more
like a sun3 than a later sparc.

I will try to load it up again tonight and see if I can find out
any details.

I have a later archive scsi 60mb drive.  Maybe I should try that instead
of the mt02/wangtek and see if that makes a difference.  The tape should
be ID 4?

Thanks!
