San Jose, California-based Radius Inc is one of Apple’s most assiduous followers and had a string of announcements including a slashing of the price of its Radius Rocket accelerator board for Mac IIs, which uses the 68040 and was clearly rather overpriced now that Apple has come out with its own 68040 machines: the cut is 42.8% to $2,000. Radius Inc also announced PowerView, an external SCSI-based colour video interface that enables PowerBook 140, PowerBook 170 and Classic II owners to connect their computers to an external colour display or large screen projection system. PowerView is a small, lightweight, video interface that plugs into the PowerBooks’ external SCSI port, enabling the machines to double as desktop systems. It supports the Apple 13 RGB display, the Radius Full Page Display, the Apple 12 display and 640 by 480 VGA displays. A subsequent software upgrade will support the Radius Pivot and Radius Colour Pivot as well. Out next month at $600. Its other offering is the PrecisionColor Display/20, a colour display for publishing, graphic design, and computer-aided design. It is a 20 multi-resolution, multi-frequency display using a Sony Corp Trinitron tube, a 0.31mm dot pitch and 24-bit colour capability. Used with the PrecisionColor interfaces enables it to be switched between 640 by 480 for enlarged or presentation views, 1,024 by 768 for actual size view, or 1,152 by 882 for full two-page view; no price or availability.
