Q:

Can 8259 he interfaced with 8085 via the trap pin?

Answer

Yes... so if 8529 gives interrupt then it will be serviced immediately but since INTA pin is left hanging the INSR bit will never be set.. and so whenever my interrupt occurs depending upon priority it 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.

Q:

What are the minimal cost and minimal risk solution?

Answer

In binary representation there are some states that believed to be never occurred due to some particular functionality of a given circuit. If zero output is assigned to such states then it is called minimal risk solution as  we are resetting the formidable states which could be occurred accidentally. Another approach is to assigned a don't care to them so it results in lesser logic and hence is called minimal cost solution.
