V7/x86 version 0.8
The first public release of V7/x86, a port of UNIX Version 7 to the x86 (IA-32) based PC is now available. UNIX V7 was the last general distribution (around 1979) to come from the Research group at Bell Labs, the original home of UNIX. The port was done by Robert Nordier mostly around 1999 when "Ancient UNIX" source code licenses first became available, and was revised for release, with some enhancements, during 2006-7.

V7/x86 currently supports ATA (IDE) hard drives, ATAPI CDROM drives, a 1.44M floppy drive, and standard serial ports, in addition to the usual PC screen and keyboard. For easier installation and setup, supplied utilities allow access to CD (ISO 9660) and FAT (MS-DOS) filesystems. Most of the source code is available under a Berkeley-style license.

Other Software
Various other items of free software, mostly intended for UNIX, are available. These include ports of a BCPL compiler to V7/x86 and of the Amsterdam Compiler Kit (ACK) to Solaris; there is an a.out based C compilation system, consisting of both existing and original components, including a UNIX-style x86 assembler; plus various disk and filesystem related utilities, and some miscellaneous code.
