It was also available as an option to the GX4000 video console.
As the disk drive of the CPC6128plus didn't needed need 12V anymore, the monitor provided a 5V power supply only.
Unlike the precedessors CTM640/CTM644 it also had built-in stereo speakers and thus a different connector for the signals.
It can therefore not be used for the [[CPC_old_generation|classic CPCs]] without adaptor cable.
