Stealing a march on the gaggle of firms rushing Unix+MS-DOS hypervisors to market for machines based on the Intel 80386 chip, Becos Industries Inc of Cupertino, California has begun demonstrating a hardware-software environment that does the same thing on the IBM AT and AT-alikes, and for good measure throws in support for Convergent Technologies’ CTOS as well. Called IntOS, the operating system is designed to enable MS-DOS, Unix and CTOS applications concurrently on an AT, and the company has been showing it off at Modular Data, NCR and Unisys facilities in the southern US this week, before demonstrating it to financial analysts in the New York City area next week. IntOS is described as a plug-in two-board set of peripherals, added memory and operating software. Set for delivery in April at around $1,500, IntOS 286 will be followed later by a version for the 80386 from Becos.
