What can I do with the speck?

Hint 1 of 5:

It's too small to examine with the naked eye.

Hint 2 of 5:

You'll need a tool to help you here.

Hint 3 of 5:

It's the small scope that Colossus is holding.  Use it on the speck to get a
good look at it.  See the appropriate section of the file if you don't know
how to get it.

Hint 4 of 5:

Then look at the speck so you can see Bizoo.  Once you do that, you're ready
to free it.
