Done, and fixed!

I made a tool out of an allen key and with a dremel, ground out the edges so that it fitted into the torx screws.

then i chopped of the other end of the allen.. drilled a hole into a small bar, and stuck the allen in there so I had made a long torx driver.. then stuck that in a cordless drill, and voila!

I took out the digital board, removed the ram and battery (Which is dead, so i'll replace that) and gently washed the whole board with a bit of window cleaner & lots of water... let it dry, then finished drying it off with a hairdryer.

My Mac still has a oscillating high pitch whine to it... like a police siren... sometimes it goes away.. has anybody heard of this before? i'm guessing maybe the analogue board is sick?

Anyway, back to getting the SCSI to work again!
