 ===== History =====
+**From Coherent...**
+Amix was not the first time Commodore attempted to build a Unix machine. Between 1983 and 1985, Commodore prototyped a Z8000-based machine called [[http://www.floodgap.com/retrobits/ckb/secret/900.html|the Commodore 900]] running Mark Williams' SVR4 UNIX clone 'Coherent' (v0.7.3). It was housed a case very much ressembling the Amiga 2000's. The machine was produced in small numbers as prototypes and developer machines relased in Europe only. Approximately 500 units were produced, with very few remaining working today. The 900 was canceled amid the purchase of Amiga during 1985.

+** ... to Amix **
 One of the first public demonstrations of Amiga Unix was at the 1988 Uniforum Conference in Dallas, TX. The prototype machine, Amiga 3500, housed in a Commodore PC60-III tower case was demonstrated at the Business Computing Show in 1991 and finally launched as the slightly re-configured Amiga 3000T in october 1991.

-The A3000UX was also sold for universities and students. The machines were generally well-received and liked by students and staff. In some universities students were required to buy required hardware and after the end of support for Amix, later on after the demise of Commodore, universities were in serious trouble finding spares to support students who had bought Amigas. In some cases universities were forced to buy machines back from their graduated students! (Thanks to Pentad on Amiga.org forums).

-Amix was sold for only a couple of years and it's support was dropped already before Commodore's bankruptcy in 1994. Rumour has it that the last (at the time only!) Amix support engineer was fired in 1993. Like several other UNIX packages of the early 1990's, Amix never managed to grab wide user base and partly due to the limited hardware support. Unlike Apple's A/UX, Amix didn't have any compatiblity layer to allow running AmigaOS applications under Unix. It also didn't make much use of the Amiga's graphic and sound capabilities, the parts of the hardware that made Amiga itself any special at the time. Also Amix's only supported CPUs (68020/68030) were underpowered and not competetively priced compared to the competing Unix workstations.

-In the early days of Amix there were talks of Sun Microsystems selling Amiga Unix machines (the prototype Amiga 3500) as a low-end Unix workstations under their brand, making Commodore their OEM manufacturer. This deal was let down by Commodore's Mehdi Ali, not once but twice and finally Sun gave up their interest.

Around the same time, there was also [[http://atariunix.com|Atari System V]], which also was an SVR4 port to the Atari TT 030 Workstation. Much like Amix, it had a "brief spark of life around 1991-92 and died shortly after".

-{{ :1990_12_byte_15-13_a3000ux_review.jpg?direct&200|}}The December 1990 issue of Byte magazine featured an article on the Amiga 3000UX with Amiga Unix. The Amiga is praised for it's complete package, and it is favoured above a NeXT, Mac or even a 386 PC.
+//"The Amiga 3000UX greatly outperforms the equivalent NeXT and Mac with A/UX. In raw Unix performance, it is roughly equivalent to a 20MHz 386 system, but it is much more suited to handling the graphics requirements of a graphical user interface like Open Look. At roughly $4000, it is an obvious choice as a low-end workstation."//
-At US$ 4000,- it outperformed the equally priced systems, but could not perform at the level of the "automobile priced" SPARCstation or Silicon Graphics machines.

+//(Excerpt from the "Using Amiga UNIX" manual)//
 Your Amiga UNIX System is a complete version of AT&T's UNIX System V Release 4.0 (Release 4) and provides all the features of that operating system. However, Amiga UNIX is more than just Release 4; it combines elements from several sources:
