9000 is also XMI. Several of them, if I remember right. SDI on the other 
hand is just a disk interface. I don't think it makes sense to include 
that here, as SDI controllers existed for Qbus machines as well, meaning 
we're now including almost everything but pizza boxes. :-)

If you were to ask me, I would find it interesting to find even 
inoperable ones. But on the other hand, I would probably abuse such a 
list to try and collect a few more bits for the 8650 machines I'm 
involved with. (More memory first and foremost.) Which might not be what 
others think would be the purpose of such a list... :-)

(I'll also happily help anyone else who want to try and get an 86x0 
machine running. There are a bunch of things people usually needs help 
with if they are trying this.)
