MCU-based encoders

One model of microcontroller-based encoder is known, DMC60C68A, based around an Intel 80C51. In an unknown catalogue entry, it is described as a “keyboard controller” but it is more likely to be an encoder. The diagram showing how to develop for it indicates that it is pin-compatible with the UM6868A.

No keyboards using this chip are known. There are however keyboards with Daewoo–Appian dual-branded chips. The relationship between Daewoo and Appian is not known.
