Toshiba Corp has duly unveiled its long-promised Sparc-based Unix laptop as the Sparc LT or AS1000/L10. Weighing in at a lap-denting 17 lbs 11 oz, the mains-powered box comes with 8Mb of main memory using 16 Toshiba 4M-bit memory chips, 64Kb cache, 180Mb disk, active-matrix monochrome LCD display putting up 1,152 by 900 pixels, and a 3.5 floppy. Rated at 13.2 MIPS, it costs $13,200 in Japan. The machine runs SunOS Unix and Toshiba sees it being used for CAD/CAM, desktop publishing systems and software engineering. It is set for first deliveries in July but Toshiba has not yet set a date for its launch outside Japan.
