* arckbd.c - Archimedes keyboard driver
*/
/*
* Most of the information used to write this driver came from the
* A3000 Technical Reference Manual (ISBN 1-85250-074-3).
*
* We keep a queue of one command in the softc for use by the receive
* interrupt handler in case it finds the KART is already transmitting
* a command (presumably as a consequence of a user request) when it
* wants to. I think this is safe in all cases, and it will never
* happen more than once at a time (I hope).
