 Name:         »keyboard vectors« - Return a pointer to the IKBD 
               (intelligent keyboard), and MIDI interrupt vectors.

 Opcode:       34

 Syntax:       KBDVBASE *Kbdvbase( void );

 Description:  The XBIOS routine Kbdvbase returns a pointer to a 
               KBDVBASE structure contaning a 'jump' table to system 
               vector handlers.

               Note: Before one of the vectors specified in the 
               structure is altered, one must ensure that a packet is 
               not currently being sent (element drvstat = 0). 
               Subsequently all interrupts should be blocked and a 
               test performed to check that there really is no packet 
               on the way.

 Return value: The function returns a pointer to a KBDVBASE structure.

 Availability: All TOS versions.
