The best it could do would be 4MHz, unless I/O wait stuff is added. I've been all through that with my design on the Z-100 and I have had a radically different design that is FAST and still worked at 5 MHz after I ripped out (gently) my I/O wait circuits. My redesign to incorporate I/O wait stuff eliminated my need for I/O wait suff... Anyway, after 4 months of grief, It works, no detectable distortion, pure sounds (The GI audio output recommended circuit left much to be desired, so I did it my way...). The thing works fantastically, much beyond what I was hoping for. I have what I wanted, and now my friends want one too. Cheers, Gern -------
