the Commodore 900 UNIX machine, that was developed inhouse by Commodore Germany(the same team would later design A500 and A2000).
C= Germany designed the ill-fated A2000A based on the orginal A1000 chips (and afaik the Sidecar/bridgeboards).
A500 and A2000B with the more intregrated "Fat Agnus" were done in West Chester.
