Sun Microsystems Inc stoutly denies a report in ComputerWorld that the 40MHz Sparcstation 10 missed its September delivery date and will not ship in volume until December. Sun says it did and still is delivering the thing in volume – it’s just not enough to meet back orders. According to what Texas Instruments Inc told us a few weeks ago, it certainly had the chips. Sun also says Solaris 2.1, due for announcement the first week of November, will get delivered starting in early December. Solaris 2.1 will run on both the Tsunamis and SunDragons Sun will launch on November 10. The Tsunamis should get delivered in short order after that, but the multiprocessing Dragons are expected to be in beta test longer than usual and they won’t go into a delivery cycle until the first half of 1993.
