Just got a big old SuperMac Tech monitor with cable (3 BNC) and a 12" Nubus card. Joe at MONITOR SOLUTIONS said he knew next to nothing about Duos(2300c) and Duo Docks so he couldn't be much help. He did say he thought the Nubus card wasn't gonna work. I put it in the dock but the machine wouldn't boot (just the chimes). It is a "synch on green", "fixed frequency" display. I have a Viewsonic adapter somewhere. Is it worth my effort to hunt it up? Milton Lukins 703-869-1421
