I hope someone has seen this problem and solved it...

As with the many peripherals I'm using on the 2148, I program the VIC 
for each to be vectored, IRQ, enabled and give the VIC a unique vector 
address.  Everything works great EXCEPT for the on-board RTC.  I always 
get a 'spurious' interrupt when the RTC generates an interrupt request; 
that is, the VIC passes off the default interrupt vector address I've 
given it instead of the vector address I programmed for the RTC 
interrupt.  I also notice that the VIC IRQ Status register has the RTC 
bit (BIT 13) set just after the VIC RTC interrupt enable bit is set.  
I've tried 1,432 different workarounds to fix this but...NO LUCK.

HELP!!!???
