;  ------------------------
; Interrupt service routine addresses to be used in RISM EPROM.
; Note:
;  Of all these interrupt vectors, only the SERIAL, NMI and TRAP vectors are 
;  required for operation of the RISM.  The other vectors are provided as 
;  fixed entry points for routines which may be loaded into RAM in the 
;  diagnostic mode.
;  In the diagnostic mode memory at the interrupt vectors is mapped to EPROM
;  so it is not possible to write into the vector table.
