G'day Joshua

 You said something about Zorro Bus?

 JM> 	I'm just wondering if anyone has some sort of a spec on the Zorro
 JM> II/III bus.  I am wanting to have a go at building a few cards to have
 JM> some fun with (eg 16-bit audio in/out, digital i/o card, serial
 JM> expansion (like 10 or so RS-232 ports))
