GBC System 9 computer

[Kelly Leavitt]

Just rescued one of these units from Craig's List. It's waiting for me a a friends house in Richmond, VA. Anyone know much about these? I think they're just a rebadged Northstar Advantage.
 
It has a bunch of software and a manual or two.
 
There doesn't seem to be a lot of information on these on the web. I did see the information at Dave Dunfield's site, and the disk archive there. Any manuals that have been scanned? I didn't see the Advantage line at bitsavers.
 
Thanks for any help,
Kelly
