This report covers development of a Bubble Memory Module as a general purpose storage unit in recorders or mass memory for spacecraft applications. Design, fabrication and test of a partially populated prototype recorder using 100 kilobit serial chips is described. Electrical interface, operating modes, and mechanical design of several module configurations are discussed. Fabrication and test of the module demonstrating the practicality of multiplexing and matrixing multiple bubble chip cells as a means of minimizing support circuitry resulting in lower power, weight, and volume. This effort resulted in the completion of a module consisting of a fully engineered printed circuit storage board populated with 5 of 8 possible cells and a wire wrapped electronics board. Interface of the module is 16 bits parallel at a maximum of 1.33 megabits per second data rate on either of two interface buses. Author
