HiSoft Systems

The business was created in 1980 and was based in Dunstable, Bedfordshire before relocating to the village of Greenfield in the same county.

Their first products were Pascal and assembler implementations for the NASCOM 1 and 2 kit-based computers, followed by Pascal and C for ZX Spectrum computers, as well as a BASIC compiler for this platform and a C compiler for CP/M. While compilers for the ZX Spectrum were typical products for this platform, with integrated editor, compiler and runtime environment fitting in RAM together with program's source, the C compiler for CP/M was typical for this operating system, batch operated, with separate compilation and linking stages.

Their most well-known products were the Devpac assembler IDE environments (earlier known as GenST and GenAm for the Atari ST and Amiga, respectively). The Devpac IDE was a full editor/assembler/debugger environment written entirely in 68k assembler and was a favourite tool among programmers on the Atari GEM platform.

HiSoft also sold HiSoft BASIC and Power BASIC, HiSoft C Interpreter for the Amiga, Atari ST, Aztec C, Personal Pascal, Forth-83 and FTL Modula-2. They also produced WERCS, the WIMP Environment Resource Construction Set.

The only game published by HiSoft was ProFlight for Atari ST (1990) and Amiga (1991).
