Anticipating the threat from Pentium Pro machines, Sun Microsystems Inc yesterday came out with a 110MHz Sparcstation 4 model 110, which replaces the model 85 and costs just $4,300 with 32Mb CPU, 1Gb disk drive and a 15 high-resolution colour monitor. People that buy in volume can get it for about $3,000. Memory is expandable to 160Mb and disk to 56Gb; the workstation also includes a new 8-bit pixelaccelerator that doubles screen speed and performance such as text, scrolling and fills. One SBus slot allows for expansion. Sun, which reckons the machine is the lowest priced fully-configured workstation in the industry, also cut the price on the Sparcstation 5 by over 20% to $9,000.
