IIRC there was a Circuit Cellar article in Byte for a 5-chip machine 
using the 8088. The other chips were, IIRC, the clock generator, 8155 
(RAM + I/O), 8355 (ROM + I/O) and an Intel RAM chip with multiplexed 
address/data buses. The address decoding was done by just connecting the 
chip enables to the high-order address lines...

Well, I've read the datasbook, I've seen it in use, but have never 
designed with it. What's the problem? It always struck me as a lot nicer 
than the 8237 + page registers that IBM used in the PC
