+/*  set_vector
+ *
+ *  This routine installs an interrupt vector on the SPARC simulator.
+ *
+ *  INPUT PARAMETERS:
+ *    handler - interrupt handler entry point
+ *    vector  - vector number
+ *    type    - 0 indicates raw hardware connect
+ *              1 indicates RTEMS interrupt connect
+ *
+ *  OUTPUT PARAMETERS:  NONE
+ *
+ *  RETURNS:
+ *    address of previous interrupt handler
