-DESCRIPTION
-Z80 computer 2 glue logic and address decoding
-/ROMEN enables the ROM for memory cycles from 0000h to 0fffh
-/RAMEN enables the RAM for memory cycles from 1000h to ffffh
-/UARTEN enables the DUART for I/O cycles from port 0 to 15
-UARTENP is the negation of /UARTEN, needed for the DUART wait state logic
-/IACK signifies an interrupt acknowledge cycle
