  Having just shipped on of these beasts to a Friend in Another
Countery(tm)... perhaps I can help a bit.

  First, it's a shame that it has to be parted out, but in truth,
there a lot of 9766s about, and they're big and heavy.. 700lb. and
220V, and delicate, and the media is expensive... oh well... still
no excuse not to love them.


  The front cover lifts from the back and pivots up at the front
panel on gas shocks. The side panels can then be removed by lifting
up on the two metal square handles on either side. Pull them up and
the sides will fall away, usually onto your foot. :)

  The electronica door in the back can be removed by pulling the
lower hinge-pin up using the little metal bar atteched to it for
this purpose. Cut or unscrew the bondong wire. Same for the front
door, and the side panels.

  The PSU slides out on regular chassis tracks, which have a clip
release at the end of the extended travel. Remove all the wiring
first, then extend the PSU until it stops, then find and depress the
tabs on the outside middle of the slide tracks and withdraw the
PSU... and watch it... it's close to a 100lbs, tho it doesn't look
like it. (If the 'braid' you mention is flat and silver, it's a
ground bonding conductor... unscrew it or cut it. If no other
tools, you can just work it back and forth at one of the connectors
untill it frays and breaks. Been there, done that, got the t-shirt.

  Take off the top inside cover and try and get the heads out... I
have never removed them, but apparently they can be gotten quite
easily. Also the head-amp card cage and associated wiring.

  If you're really ambitions you could remove the HEPA filter and
the disk spindle assembly... the rest of it's scrap at this point.


   snif,,snifff.. :(


  Hope this helps a little.

  Cheers

John
