Hi
The two IRQ are via the VIC. The instruction at address 0x18 is;

LDR PC,[#-0x0FF0]

which should be fine. All the other IRQs are OK. Once the stall 
occurs the program is still running. The normal code is stepping 
through with no problems, its just that the interrupts are not being 
actioned.

Very odd...

By the way, you mention a new errata posting by Philips. I am having 
trouble finding it, would it be possible to pass on the location?

many thanks
Simon
