I'll second that!  I sure with I could buy a prototype board that
would autoconfig to 64K of decoded address space, buffer the data bus,
and give one irq/ack pair (switchable to either interrupt level).  64K
is enough address space to interface most projects (EPROM, or shared
memory buffers to a coprocessor, or whatever) but not so much that a
two-address I/O chip will use up lots of autoconfig space.

It would take about five chips to do this, and cost about $50-$100 to
produce in medium quantities.  I will buy a few if someone makes
them...

Or, at least, C=A should publish a PC layout and PAL equations for
such a thing.
