Description
KKQ Type is externally identical to the better-known Mitsumi KPQ Type; where KPQ type uses a single membrane sheet for the keyboard matrix, KKQ type uses a PCB. KKQ type is known from Commodore keyboards. No specifications for KKQ Type have been recovered.
It appears that the primary advantage of KKQ Type over KPQ Type is that the use of a PCB permits diodes, for N-key rollover. However, as a KKR keyboard has been found without diodes, this appears to be an optional feature.
