Can 8259 be interfaced with 8085 via the trap pin, Computer Engineering

I think yes...so if 8259 gives interrupt then it will be serviced instantly but since into pin is left hanging the insr bit will never be set...and so whenever any interrupt occurs depending upon priority itt will be serviced....also the isr address for all interrupts will be same ie 0024H...

Interrupt via trap is nonmaskable, so it will be serviced immediately.
