Sun Microsystems has never formally acknowledged that it is working on a line of 80386-based workstations, but an agreement announced yesterday with Daisy Systems Corp, also in Mountain View, California, confirms that an implementation of the SunOS version of Berkeley Unix with System V is ready. Daisy has taken a licence to SunOS that extends its use of the operating system to its 80386-based workstations as well as its Sun-4-based XL Servers, which acts as a network computing node for printed circuit board routing and analogue simulation, and began shippin in December. The 80386-based products include the Personal Logician 386, Logician 386, and Megalogician simulation accelerator. Initial release of SunOS on Daisy workstations is expected in the second half of 1988. Daisy is also incorporating the TCP/IP protocol and Sun’s Open Network Computing/Network File System, and plans to implement the X11/NeWS graphics interface standard. Upgrade paths and conversion options are being offered to users of Daisy’s older 80286-based workstations: they can be upgraded with an 80386 processor, users who retain their Daisy DNIX systems can connect them to the same physical network and share files and network resources with the Unix workstations. Daisy will offer X-Window with its initial release of SunOS, and plans to migrate to X11/NeWS in a subsequent release.
