|

Serial keyboard emulation for Sanyo MBC-55x.
|
||||
|
||||
The key matrix is based on schematics, though the MCU is not yet dumped.
|
||||
Many keys are not yet implemented, as are the Lock and Graph key LEDs. The
|
||||
unknown jumper may select an international key layout.
|
||||
|
||||
The interface has only one unidirectional communication line. The reset
|
||||
switch appears to be part of the main unit rather than the keyboard.
