DISCIPLE
FOR ZX SPECTRUM 48K  OR  128K
FROM MILES GORDON TECHNOLOGY (MGT)

DISCiPLE, Miles Gordon Technology's first product, was a floppy disk interface for the Sinclair ZX Spectrum home computer.

Like Sinclair's own Interface 1, the DISCiPLE was a wedge-shaped unit fitting under the Spectrum. It was designed as a super-interface, providing all the facilities a Spectrum owner could need. In addition to floppy-disk and parallel-printer interfaces and a "magic button" (see Non-Maskable interrupt), it also offered twin joystick ports, Sinclair network ports and an inhibit button for disabling the device.

At the rear of the unit was a pass-through port for connecting further devices.

The DISCiPLE was a considerable success but its sophistication meant that it was expensive and the plastic casing, located beneath the computer itself, was sometimes prone to overheating. These factors led to the development of the +D.

The DISCiPLE's DOS was named GDOS. MGT's later DOS systems (G+DOS for the +D, and SAM DOS for the SAM Coupé) were backwards-compatible with GDOS.
