Unix Multiprocessor

I have this mouse-pad swag somewhere.

The
Product

Know officially as SVR4.2MP / UnixWare (See history of Unix System V https://en.wikipedia.org/wiki/UNIX_System_V) for reference) this was the first UnixWare release for multiprocessors. It was a large re-write of the kernel, especially the virtual memory portion, to run on a multiple processor machine.
