Awesome thanks, I plan on going to Component out eventually to my CRT, for now it'll be going to my HDTV assuming that's easier to set up?
If you're deciding to go to a crt, you'll need the I/O board eventually.
You no longer require the I/O board if you want analog to a Crt. You can get analog out of the Hdmi port with a feature called direct video.
Of course I find the main board for $50 cheaper on Adafruit but they stopped shipping orders last week. Bah.
