Quoting from BYTE September 1990, from an article "The creation of the IBM PC" by David J. Bradley (who worked on the development of both the DataMaster/23 and the IBM PC): ============================================================== The DataMaster was an Intel 8085-based system intended to run business applications written in BASIC. The one-piece DataMaster was a business-oriented single-user system. It served as a model for many of the features of the original IBM PC. The IBM PC keyboard came from the DataMaster. ============================================================== Sorry, no scanner in the house, so I can't send you a copy. Freek Heite.
