(Quoted from Wikipedia)MacMach is a computer operating system from the early 1990s. Architecturally, it consisted of 4.3BSD code running on the Mach microkernel, with the Macintosh System 7 running experimentally as a Mach task. The entire system ran on Macs based on the Motorola 68k family of microprocessors.
Is there any more info about this strange oddity? Was it ever released?
