Geoff, Greg is correct, the 2300 board was designed to be able to upgrade any of the previous duo's before it. Because of this design, the 2300 has a connector for the colour and the black and white screens of the duo's before it. Not only are these boards able to use either monitor, they are also compatible with IDE and SCSI hard drives. Blake.
