I traded for this a loooong time ago to use with my Monster PPC 4000 and Diavolo....it got no use at all because I never had the time to set it up.
External unit with 50PIN Centronics style SCSI and terminator. Has a min-din to 50PIN centronics cable too.
I believe there's only one cartridge in the box.
It's boxed and looks virtually brand new.
No idea what this is worth since I traded it.
