The Seiko MC-2200 was a clone of the Sharp PC-1245. Besides, it was made by Sharp.
The main differences were the case color, black instead of grey and brown for the Sharp, and the location of the 16-character display which was slightly moved to the right. The internal electronics was identical to the PC-1245's
The tape-printer interface was also the same as the Sharp CE-125 but with black and grey colors
This rare machine seems not to have met a great success.
