dps8m for Mac

dps8m is a command-line emulator aimed at retro-computing enthusiasts and historians of mainframe computing, recreating on ordinary computers the runtime environment of the GE, Honeywell, and Bull 600/6000 series 36-bit mainframes. These machines played an important role in enterprise computing in the 1960s and 1970s; physical equipment is now hard to find, and dps8m lets those old systems and old software keep running on contemporary hardware. It suits people interested in early mainframe architecture who want hands-on experience or study of that period of computing history, as well as developers who need to run or debug related legacy software. The tool operates through the command line, with a plain style, leaning toward technical exploration rather than everyday use.
