I should warn you that all the plastic latches and such will be very brittle. proceed carefully.
That's a good place to start, and I second the cautionary warning about parts being old - but
that applies to all older comps.
Here's another place to look for instructions on taking it apart:http://atari.st-kath...y&texte=S_STacy
Don't be afraid of it - you just need to set aside a good amount of time so that you're not rushed
and be careful. Take pictures of things before you take them apart, have plastic trays with labels
to put your screws/bolts/parts in, etc,...
