SunSoft Inc is going to support Microsoft Corp Windows 3.0 applications under its Solaris 2.0 Unix System V.4 implementation, according to SunSoft president Ed Zander, speaking at SunWorld Expo a couple of weeks ago. However, the company hasn’t decided whether support for the environment should be available as a third party offering or whether it should stick the technology into Solaris itself. Quorum Software Systems Inc, the Menlo Park, California outfit that has al ready done a version of its Compatibility Engine – enabling Apple Macintosh programs to run on RISCs – for Solaris, is currently negotiating terms with SunSoft to do a similar Windows product, saying it would be an easier job than the Macintosh version.
