The Symmetrix Manual for the 375

The Symmetrix Manual for the 375
Lynne speaks - "The Symmetric 375 was a very unique computer. Based on the NS32000 microprocessor, it was a portable no wait state computer with virtual memory, hardware floating point, large processor main memory, and ethernet. Unlike PCs, it supported 4 users easily with a host of compilers, debuggers, tools and utilities, and applications. It ran a custom version of Berkeley Unix (4.1BSD, 4.2BSD, 4.3BSD) called Symmetrix. Later versions offered a configurable kernel software package for device drivers and SCSI support. Much of this work influenced work later done in 386BSD. I wrote the "The Symmetric 375 and Symmetrix Owner's Manual" for it.

One of the most interesting aspects of this manual was that it did not follow the typical "Unix Man command" style. Instead of offering a printed command manual with some hardware pages as was the common approach, the 375 came with an online man function (early UNIX boxes often didn't do this to preserve disk space).
