Aries Research Inc has introduced its Sparcstation 5-compatible system as the 85MHz Marixx MS/85: the microSparc II MS line will replace the Fremont, California company’s existing Parrot Sparc line. MS/85 users will be able to upgrade to Sparcstation 20-compatible systems via a motherboard swap, the company says. The MS/85 with up to 256Mb RAM, three Sbus slots and support for two hard disks starts at $3,800 and ships in the third quarter.
