QUADLINK

The Quadlink is a product of the Quadram Corporation. Featuring 64 kB of RAM and a 6502 processor, and supporting both low-resolution and high-resolution graphics modes, it is essentially a clone of the Apple II Plus. As such, it does not support the double high-resolution graphics mode of the later Apple II line. Furthermore, its RAM cannot be expanded to 128 kB.

The Quadlink requires a connection to the PC's 5¼” 360 kB floppy drive in order to read and write Apple II floppy disks. It is unfortunately not possible to connect an authentic Apple Disk II floppy drive to the Quadlink, for enhanced compatibility. The Quadlink can output video in one of two ways: directly to your PC's CGA monitor, or via composite cable. For the former option, a custom cable “intercepts” your PC's video, which is then output by the Quadlink itself. The Apple II sound, meanwhile, is routed through your PC Speaker via a 4-pin cable.
