It starts up via the RESET vector at $FFFC, $FFFD. I believe the 65816 powers up in Emulation mode, so you'd find its reset vector at 00/FFFC, 00/FFFD. Note that the CPU has to be reset when its turned on, to put the processor into a known state. UUCP: crash!pro-generic!sb ARPA: crash!pro-generic!sb@nosc.mil INET: sb@pro-generic.cts.com
