A full length card which plugs into both a Zorro II slot and an ISA slot. It lets your Amiga run PC software as fast as a real 486. The card also contains an onboard external disk drive connector, IDE controller and an option connector for use with the Monitor Master. This card can use any real ISA card plugged into the ISA slots from the PC side. Apparently 2 or 4MB of memory can actually be allocated for use by the Amiga and some Amiga memory can be allocated for use by the card, but this must be 24bit memory only. The card was supplied with an optional 2.88MB floppy drive controller, however the Amiga's native floppy drives can be used as if they were 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, as this card requires a capacitor across two of the 68000 pins. This vortex board allows you to have up to 24 partitions on the PC card.
