[cctalk] DEC VT180 "Robin" Maintenance Prints?

Does anybody have the maintenance prints for the DEC VT180? The VT180, aka "Robin" was DEC's CP/M machine in a VT100 chassis. The terminal part is just a standard VT100 and maintenance prints for that are easy to find, but I need a schematic for the actual Z80 CP/M Robin option card. Can't seem to find that anywhere. Bitsavers and Manx have the technical manual which has some information (although it wastes way too many pages explaining how a VT100 works!) but no actual schematics. On the same topic, has anybody dumped the ROMs for this machine? Again, not the VT100 ROMs, but the CP/M boot/POST ROMs that are on the VT180 Z80 card. Thanks, Bob
