[sdiy] Some old IC's

[Senso]

>(8 pins) has the following text on it: 4558DV JRC 1468.

That's a JRC 4558DV, a common dual op amp, also known as NJM4558DV. 
I'm sure Google will come up with a datasheet.

Is that all it says? Nothing else?

Never heard of that one, but judging by the number, it's a pre-DX7 chip.
