Elsewhere on their site they say that the 400mhz is out of stock but that they have limited quantities of the 500mhz.

The Crescendo 7200 is not the Crescendo Nubus.
"May require Crescendo AV/HPV Card Video Adapter" wich is $19.95 extra.
You *only* need that ribbon cable if you want to use the G3 in a 7100 or 8100 *and* use the Apple AV or HPV video cards. In a 6100, it is not required (the AV/HPV plugs directly into the G3, at right angles; the G3 card takes the place of the 6100 PDS right angle adapter), and in a 71/8100 you have the option of using a Nubus video card instead. Even with the ribbon cable, the AV/HPV card uses up a Nubus slot for back-panel mounting, unless you get creative.
