Can't Find Parts On Google (Pico-78567)

Well as any amateur would do who isn't taking a collage course on electronics engineering, I'm pretty much taking apart old electronics I don't use any more and see how they work.

I've come across a few parts I've never seen before on this X-10 Mini Controller. I wanted to see how it sends signals and convert 120V 60hz of AC to a friendlier current for the IC inside the Mini Controller.

I'll list some of the part's numbers and names if someone can help direct me to a website or a place that would show more information.

Model Number: MC460

IC: Pico-78567 8950
R1: 2.2K 250V CMC (I assume this is what is changing the current to be 'DC' friendly)
R2: .22K 250 CMC

Since this Mini Controller must be almost the same age as me, I presume the parts inside are not made anymore. I'm really interested on how the Pico works and where it came from. Google is a great search engine, but it doesn't seem to help me to well, so I was wondering if anyone here has experience working with this IC.
