Abstract

In the work of this thesis, microprocessor, - based software and hardware have been designed to perform the functions of the PDP - 9 Dectape controller. For 8-bit data transfer, seven functions were implemented in software that simulate the move, stop, search, read, write and formatting functions of the PDP - 9 Dectape controller. The hardware is designed to interface the Dectape Transport with the microprocessor, as well as to amplify and temporarily store signals. The new controller is implemented with an inexpensive Motorola 6800 microcompuier. Hence, the Dectape transports can be used with any computer or with special, experimental apparatus. Sixteen-bit transfer was also attempted but the resulting system still requires more testing and development.
