Fairlight-CMI

Hello to all users,

yesterday I posted the problem that my IIx has since I wanted to use 
it again this week.
I digged deeper and can now describe the problem more precisely:

After I had removed all the cards because it refused to boot 
completely, it now boots again but doesn't recognize any voice cards 
any more. No matter if I have two, four or all 8 cards in the machine.

Maybe the other problem is a follow up on the missing soundcards: The 
machine has booted, I can go to all pages, they all look like they 
are supposed to, but once I have been to page three "Keyboard 
Control" and then try to go back to page two "Disc Control", the 
machine freezes or displays strange characters.
The page three, that seems to cause this problem, doesn't display 
properly but looks like this

Any ideas ?

If I try to change the "0" under the first "6" in the lines of sixes, 
it also crashes with a task error.

Help would be really appreciated because in about three weeks there 
will open a Dieter Meier (of Yello) exposition here in Karlsruhe, 
Germany at the ZKM and we were thinking about the idea of presenting 
Yello's most important music tool of the 80ies. Preferably in working 
condition :-)
A friend of mine works at the ZKM and asked me about my CMI for this 
occasion which I haven't used for quite some time. The last time it 
was working properly.

Apple monitor connected with Joe Britt's excellent interface box.

Thanks a lot

Cheers
