Solid state music player using signals from a bubble-memory storage device

A solid state music player for reproducing and playing stored digital information from a magnetic bubble-memory device having exposed terminals, comprising:

• a bubble-memory module for receiving the bubble-memory device, which contains the stored program;
• a function-timing generator, which is coupled to said bubble-memory module for generating control and timing signals for said module;
• a bubble-memory controller coupled to said function-timing generator and said bubble-memory module;
• a microprocessor coupled to said bubble-memory controller the bubble-memory controller responding to commands from the microprocessor, to send control signals to the function-timing generator, necessary to access the digital data stored in the module, and reading stored digital information from said bubble-memory module, the controller performing a serial-to-parallel conversion of the stored data as the data is transmitted from said module to said microprocessor;
• a digital-to-analog converter coupled to said microprocessor for converting the stream of digital information from the microprocessor into the analog signals;
• amplifier means coupled to said converter for amplifying the converted analog signals;
• a housing having a plurality of receptacles disposed in its top surface;
• and
• a plurality of electrical contacts coupled to said bubble-memory module and disposed in each of said receptacles along its peripheral walls, for contact with corresponding terminals on the bubble-memory device.
