I'm not familiar with the RS version of this device, but I have used the
Dallas Semiconductor (DS1200) with success.  I had it working with an 8051
as the CPU, so a Z-80 shouldn't be any trouble. I can supply a listing of
my code if that is helpful.  Also there was an article in Byte by Steve
Ciarcia using the 8052-Basic chip.  Contact me via email for further info.
