 Many ADB keyboards has no discrimination between right modifier and left one,
 you will always see left control even if you press right control key.
 Apple Extended Keyboard and Apple Extended Keyboard II are the examples.

 ### Pull-up Registor
 You may need pull-up registors on signal lines(`CLOCK`, `DATA`) in particular when you have long or coiled cable. **1k-10k Ohm** will be OK for this purpose. In that case the converter may not read signal from keyboard correctly without pull-up resistors.
