Expansion modules for the ColecoVision are also incompatible, as the expansion port uses the pin configuration of the SG-1000. Subsequently, ColecoVision games that rely on expansion modules cannot be used, but the machine is compatible with the SG-1000 keyboard.
Due to a difference in pin configurations, expansion modules for the ColecoVision are incompatible and cannot be used with ColecoVision games. However, the machine remains compatible with the SG-1000 keyboard.
