IBM Corp had an intriguing little demonstration tucked away on its booth at PC Expo in New York last month – an MS-DOS personality running on the Workplace microkernel running on one of Power Personal’s prototype machines. Details of the MS-DOS emulation are sketchy. An IBM spokesman said that the technology demonstration was shown running a few MS-DOS applications, but could not say whether these were off-the-shelf or specially written for the event. The machines did not seem to be running any form of benchmark that could indicate the speed of the emulation. Unfortunately, we missed the occasion, but we are keen to hear from anyone there who saw that C: prompt in action.
