It’s usually many moons between the showing by Commodore International Ltd of a product idea at a show and the availability of the thing, so it is not clear when a 68030-based upgrade board and a version of Unix System V.3 for the Amiga 2000 will be available, but the things were at Comdex/Spring in Atlanta this week. According to Microbytes, the Unix uses a proprietary windowing system on the Amiga, and was shown displaying two windows with shaded, three-dimensional-style borders while scrolling a file rapidly underneath the windows. Unix will not be able to co-exist with native AmigaDOS applications because it uses the machine’s 68000 family CPU; MS DOS can run concurrently because it uses a co-processor. The 68030 CPU and memory management board supports up to 20Mb of memory. A high-resolution mono monitor for Amigas has 1Mb of its own memory, putting up 1,008 by 800 pixels. Transputers are also in the Commodore plan.
