DevPac was a professional integrated development environment created by HiSoft for the Amiga platform, combining a macro assembler and debugger specifically designed for Motorola 68000 (68K) assembly language programming. The package typically included the DevPac Assembler and MonAm (Monitor/Debugger), providing developers with essential tools for low-level system programming and hardware-banging demos. It became one of the most popular development suites in the Amiga scene during the late 1980s and early 1990s, prized for its reliability and comprehensive feature set.
