]You may be missing a critical point.  One of the reasons that Macs are friendlier
]is that they don't have the 8086 baggage with 16 IRQ's (of which only about 5)

The 8086 family has no such restriction: it's in the design of the 
    motherboard and the use fof PICs and how they're cascaded.

In any event, 16 (15 actually) is plenty: the AT (ISA) bus design is the 
    problem as each interrupt has to be handled before the signal can be 
    used for another interrupt.
