Xinc Electronics, Clearwater, Florida, is aiming to supercharge the older and less powerful Sun Microsystems 68020-based work stations with the Sparc Plug, which it claims to be the most powerful hardware and software upgrade available for Sun systems. Due to be unveiled at an IEEE conference in Orlando, Florida this week, the Sparc Plug box is built around Solbourne Computer Inc’s Cypress Sparc CPU and slides into a VME slot on Sun workstations. It is claimed to boost the performance of a 2 MIPS Sun-3 system to over 65 MIPS, and the company has also plans for a version built around the 64-bit version of the Sparc being developed by Matsushita Electric Industrial Co, which will go to over 100 MIPS. Xinc will be offering two and four processor Sparc Plugs built around the corresponding Solbourne Series 5 boards, which come with an interface card for the S-bus and software from Solbourne’s implementation of the SunOS operating system – no prices were available.
