 - Literally all PS/2 keyboards can be handeled the exact same way. We have the capability for detecting different keyboard types, I just don't bother with it because that would litreally take months to get working.
+- The device doesn't send any data while we're waiting for an `ACK`.
 
 Supporting mice in the keyboard port and vice versa was a ***bad*** idea, but I do not regret it because it means we're "superior" to real world operating systems.
