The JAWS machine will always have special sentimental value to me because of the Andy Grove experiences, the Steve Jobs experiences, demoing JAWS on Computer Chronicles, etc. My instance of that machine has also been of practical value for my testimony at a hearing in a patent matter, and in preparing Windows 3.11 machines for other patent matters.

[update December 2020: Dell Unix on 86Box “Today let me present Dell Unix more properly, with 1024×768, 256 colors video and proper networking using emulated VGA and NIC.”]

Dell SVR4 User Guide

Dell UNIX originally ran on hardware from almost 30 years ago, with almost all peripherals dependent on the (now long defunct) ISA bus. Though such hardware is still available on eBay, from recyclers and others, the door is closing on sustaining Dell UNIX on bare metal. Thanks to Antoni Sawicki’s Qemu/Bochs & Virtual Box efforts, perpetuating Dell Unix on virtual machines is much more practical. However, SLIP will never cut it for network access when even 10BaseT seems painfully slow. For several years I’ve been intending to try to get an Ethernet driver for a card supported by Virtual Box emulation, probably an AMD Am79c970. (more…)

[Update 12/7/2022: “Warren Toomey receives the 2022 USENIX Lifetime Achievement Award for founding and maintaining tuhs.org, The Unix Heritage Society, which for three decades has provided a forum for discussion of the history of Unix and a repository that collects, preserves and makes available to the public documents, bibliographies, source code, web links, and personal recollections pertinent to the evolution of this most influential of operating systems.”]

“A very good place to start” – Oscar Hammerstein II

IBM 801 Building ca. 1975

Late last year I became aware of “The Unix Heritage Society”, a fascinating archive and mailing list on UNIX history (and often, tangential topics). Even Ken Thompson occasionally contributes.

There have been various TUHS discussions of AIX in the 1980s, the RT/PC, etc. Often I want to say, “no, that’s not how it was, or, at least, not how it seemed to me when I was in the middle of things”, but I’ve avoided joining those discussions.

Since I don’t know of a good history of AIX, nor the associated hardware projects prior to the RS/6000, this is my attempt to say what I can to clarify and fill in the lesser known history. (Peter Salus’ A Quarter Century of Unix is a comprehensive reference, but barely mentions AIX. The RT book is a snapshot at the time of the first release and only incidentally covers history. AIX Turns 20 reflects on the first two decades.¹)

VMware Server 1.0 wasn’t broke…
