PDS development system
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, C64 and Spectrum. The code was written on the PC and transferred through the hardware interface to the target computer.
The target computer ran a program which waited for PDS to send it instructions.
