GESPAC SA was a Swiss company who designed the G-64/96 Bus in 1979. This interface bus concept provides a simple way to interface microprocessor modules with memory and peripheral modules on a parallel bus. The G-64/96 Bus uses a simple, yet modern and powerful interface scheme which allows a higher level of functionality from the single height Eurocard form factor. The low overhead of the G-64/96 Bus interface greatly eases the design of custom boards by the User. This is why, even many years after its invention, the G-64/96 Bus is still widely used in the industry.
