Robbie: ICs

I found some of these ICs amidst my heaps of circuit parts and found out what some of them are. I would have shown more but the camera died...

<741> I have two of these. (basic amplifying IC as name sugests)

<339> I have two of these too.  (this is four of the 741 stuck together)

These two I have no idea what  they are. All I know is that they have 14 pins. If you know post a comment on what it does and how to wire it up.

When I get a bredboard I will show off some circuits.
