UNIX/32V

UNIX/32V is an early version of the Unix operating system from Bell Laboratories, released in June 1979.

DEC then approached a different Bell Labs group in Holmdel, New Jersey, which accepted the offer and started work on what was to become 32V.

[1] Performed by Tom London and John F. Reiser,[2] porting Unix was made possible due to work done between the Sixth and Seventh Editions of the operating system to decouple it from its "native" PDP-11 environment.

The 32V team first ported the C compiler (Johnson's pcc), adapting an assembler and loader written for the Interdata 8/32 version of Unix to the VAX.

"[3] UNIX/32V was released without virtual memory paging, retaining only the swapping architecture of Seventh Edition.
