WTF? Where do you see "OS compatibility"? The issues that I raised were all 
architecture and instruction set.

If you are going to include OS compatibility as well as hardware
compatibility then there are issues such as control blocks that have been
moved above line.

That's not the only thing. A program that relies on getting certain program
interrupts might fail. Then there's the ASCII bit, although I would be very
surprised if anybody actually used it. There are optional instructions that
IBM carried over. There's probably more that I haven't thought of.
