Fail Trap (consideration)An interrupt called on Fail condition.
This is different from hardware interrupts. Those are requested though channels INT lines and have fixed vector addresses in page zero: 0x000 for channel 0 ... 0x00f for channel 15.
This must enter the Interrupt Controller directly and must also have a fixed vector address, possibly at 0x010.
It must also have a dedicated bit in G register (ftrap) that can be enabled, disabled by software.
Maybe a toggle switch in the Console: TOF (Trap On Fail) to manually enable/disable this trap.
