PDS is an acronym for "Programmers Development System" and is a development system made by [[Andy Glaister]].
The system comprised an "[[Apricot PC]]" (an early PC), assembler, debugger, editor, profile, graphics tool and hardware to connect to a target computer.
A company called "Programmers Development Systems Ltd" or "PD Systems" sold it.
The system made it easy to develop for computers like the Amstrad CPC, [[Commodore 64|C64]], [[MSX]], and [[ZX Spectrum]].
The code was written on the PC and transferred through the hardware interface to the target computer.
