Models

MCK-18
Direct matrix interface using a DA-15 plug to attach to the back of an Ortek MCK-84 keyboard[1] with Alps SKCM White switches;[2] the exact model number is not verified

The direct matrix version has been confirmed to have a plate and PCB with positions for 22 keys, and the lower case is marked "MCK22"; this implies that the MCK-18 and MCK-22 shared parts. There is no other internal markings indicative of manufacturer or model, and it has no controller chip.
