By 1977, CP/M had become the most popular operating system (OS) in the fledgling microcomputer (PC) industry. The largest Digital Research licensee of CP/M was a small company which had started life as Traf-0-Data, and is now known as Microsoft.

Source for OUP/M - a CP/M-like operating system for 6502

Original source here:https://archive.org/details/OUPMA6502OperatingSystem

My goal is to compile a binary for emulation.

From the original:'In the development of OUP/M, an OSI C-3 microcomputer system was used. This system consists of a 6502 CPU, a dual 8-inch floppy disk drive, a console, a printer, and 56 K bytes of RAM. On this machine all I/O is memory mapped and address space layout has to be taken into consideration.'
