Microport Unix

Microport SYSVR32 boot

Microport's System V/386 made by Microport. Plain vanilla version, very close to AT&T 3.2 sources. No BSD extensions, no X Window. SGS and TCP/IP are not available (yet?).

Available at archive.org: binaries and documentation

May fail on many emulators, it does something strange with emulated VGA. To avoid this, choose a machine configuration with CGA display adaptor.

May fail on emulated i386. Select a i486.
