The Gold Card was the first Miracle Systems board to replace the QL's 68008 processor. With 2MB RAM and a 16MHz 68000 processor, it could roughly quadruple a QL's performance. 1920K of the memory is directly available to the QL; the remainder is used for display memory and shadowing the QL and Gold Card's ROMs. The Gold Card has a disk drive interface connector capable of supporting up to three disk drives. Double Density (720K), High Density (1.4MB) and Enhanced Density drives were supported, and the connector was backwards-compatible with the older Miracle Systems Trump Card. The Gold Card has a battery backed clock, whose time and date are copied to the QL's inbuilt clock at startup. Supplied on the built-in ROMs were the Toolkit 2 and level 2 directory drivers for floppy discs and RAM discs. The Gold Card attaches to the QL via the standard interface slot.
