Fairlight-CMI

Actually, while Im in a posting mood, I was wondering if I could ask 
a few questions to the group.....

1) I want a nice way to backup to voice files. I had heard I think 
that some people had got scsi zip drives working with their series 
3's. Is this a good way to do it ? WHat device do I need ?

2) I changed my processor card, and now have a fault whereby all of 
the 2mb memory boards cause digital distortion accross, the system 
when plugged in. I also have 3  x 8 mb cards. Running with just the 
8mb cards, the system runs perfectly. Has anyone come accross this 
issue and knows anything about it ? 

3) My pen pointer skips around the screen a bit. Sometimes its OK, 
and sometimes not. I thought I had fixed it by plugging the alpha 
keyboard directly into the mainframe, instead of chaining through the 
music keyboard, but it still happens every now and again. Any ideas 
on how to resolve this one ?

Cheers,
