Help, please, with Samson CO2

[frogmarch]

I just bought the Samson CO2 pencil condenser microphone, which is actually two small mics. The information that came with the set included no instructions for recording, nor was there a cable. I have no idea how to set up the CO2 to record on my computer - which I've been doing with Audacity, using my Samson CO12 microphone. My Celtic harp doesn't record well with the CO12, but I've read that the CO2 does a fine job of recording stringed instruments, including harp.

As anyone reading this can tell, I don't know much about this technical stuff. I'd appreciate it if someone here could tell me what kind of cable, etc., I'll need to buy, and how to set up the CO2 to record on my computer.

Thanks in advance!

1. In case anyone's interested,

after much googling, I learned that in order to record with the CO2 mics, I'll need an interface to convert the mics to digital info for my PC.

Shucks.
