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.
