I've put this driver on my web page at :

http://phaedra.apana.org.au/johna

But, my original comments ommitted the fact that there is a data in
pin, as well as a data out pin. The code itself is fine, and reflects
this.

The correct pin allocations are :

port 0x278

bit 0, pin 2, Clock
bit 1, pin 3, Chip Select
bit 2, pin 4, Data out to ADC
bits 3-7 user available

port 0x279

bit 3, pin 15, Busy
bit 4, pin 13, Data in from ADC
bits 5-7 user available

And I've changed the code on my home page to reflect this.

Gatic,
