Kevin Wandryk, product line manager for the new release, said the PC-DOS mode in the new release increases the availability of applications software. End users can choose between products for Concurrent CP/M or PC-DOS. Digital Research will provide a list of those applications from PC-DOS which may be used, Wandryk said. The manufacturer's version was introduced in December at the COMDEX/Fall trade show in Las Vegas and is scheduled to ship in March."
