From Motorola 68000 Homebrew Computer Project
I plan on writing a basic operating system called ZeDOS for the computer. The name ZeDOS comes from the OS I made for my old Z80 system and the 68000 will be ported and expanded from the Z80 version.
ZeDOS is something of a mix between DOS and Unix philosophy, utilizing drive letters (A:/B:/C:/etc.) but still following the "everything is a file" philosophy.
Z: is the "system drive" containing what you would normally associate with devfs and procfs filesystems. For example:
A serial port might be: Z:/dev/ser0
A hard drive might be: Z:/dev/hda
Similarly, you might see:
