External drive, tape for Sun 3/80

Wed Nov 22 08:10:07 AEST 1989

I've received my new Sun 3/80 and am feeling a bit cramped by "only"
having the two built-in 100 Meg drives.  Can anyone recommend a supplier
for a reasonably priced expansion box containing a 300 Meg drive, and a
cartridge tape?  (I'm sorry if I missed the discussions of this.)

Also, does the Sun 3/80 use a newer SCSI protocol (synchronous?), which
would not allow me to interface to an old-style shoe-box?
