RISC-5 has some reserved address space from $FFFF00 to $FFFFFF, some
used by H/W mapped registers for I/O.
I was thinking, to use some of those for `VID.v' clipping.
Procedure `Clip()' would fiddle with some of these reserved addresses.
Is it worthwhile, or
just bad idea, difficult, complex or costing many cycles, and
