These are the connections found at the side of the Amiga 1000 and Amiga 500 computers. They are electric and mechanical compatible with the single exception of being rotated 180 degrees looking at it from the top of the PCB this can cause trouble connecting a expansion meant for the A1000 into the A500 and vice versa. This Bus is like most Buses at this time a extension on the CPU Bus.
