two IACK pulses, and the interrupt vector is issued as a response to the second one. The
vector’s source the OAK mailbox vector register (OVEC). The value stored in this
register is determined by the OAK, by writing operation.
IREQ is not deactivated by the IACK pulses directly, but by P writing access to OBUSY.
