Vortex Golden Gate 486slc

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. This card is basically the same as the 386 version, but uses a 486 instead.

CPU: Intel 80486SLC@25Mhz
RAM: 2MB (Expandable to 16MB)
Ram Type: 30 pin SIMMS (Must be added in pairs)
Controller: On board IDE interface.
Ports: LPT1 (Parallel), COM1 (Serial)

This card also allowed the use of ANY PC ISA cards plugged into your ISA slots, from the bridgeboard, and has an optional Extra High Density floppy controller (2.88MB) with an option for an FPU. The native Amiga floppy drives can also be used in conjunction with the board as PC drives.

This card requires a small adaptor if used in an A2000, which was usually supplied with the card. This involved removing the 68000 processor on the motherboad and seating it in another socket, because this card requires a capacitor across two of the 68000 pins.

Supports 27 emulated video displays including CGA, EGA and VGA mono, Hercules, Olivetti, Toshiba,as well as support for ISA graphics cards.

One jumper allows you to share 2 or 4MB of RAM on the card with the Amiga. You can also use some of the space on the Amigas hard drive for use with card. The space can either be in the form of a dedicated partition or as a hardfile. This vortex board allows you to have up to 24 partitions on the PC card. Should you not wish to use your Amigas hard drive, this card has a dedicated IDE controller for connecting a hard drive directly to the card.
