Sun Microsystems Inc tomorrow adds a 200MHz Ultra 1 workstation to its line. The Model 200E, with 500Kb cache will start at $27,000 in entry-level configurations, some $4,000 ahead of the 167MHz Model 170E. Motherboard upgrades are $9,000. Sun is also reducing the number of Ultra workstation configurations it offers – there are currently 12 – by dropping a 128Mb memory option. It says falling memory prices mean users buy low memory configurations and add cheap upgrades. It’s offering 32Mb RAM for $800 – almost half what it used to cost. It says sales are bone-shaped – slewed towards the high-end Ultra 2s and low-end Ultra 1s.
