The Bridgeboard is a full length Zorro II card that will let your Amiga 2000/3000(T)/4000(T) computer system run MS-DOS and Windows compatible software. CPU: Intel 80486SLC@25Mhz RAM: 2MB (Expandable to 16MB) (30pin SIMMS) Controller: On board IDE interface. This card also allowed the use of ANY PC ISA cards plugged into your ISA slots, from the bridgeboard, and has an optional High Density floppy controller with an option for an FPU. This card requires a small adaptor if used in an A2000, which was usually supplied with the card. Supports 27 emulated video displays including CGA, EGA and VGA mono, as well as support for ISA graphics cards. One jumper allows you to share up to 4MB of RAM on the card with the Amiga.
