I hate to tell you this, but...

Z85230 is still a silly ZS chip :-) And as you say later, it's four
ports (2 ZS chips of 2 ports each).
Good news is that the '230 has a deeper FIFO, so it should be better
than the stock ports. Also, writing a drievr should be easier, since you
just need a way to attack the existing zs driver to those chips.
