This is incredibly fascinating. The one thing I don't get is how the Cartrivision was used to record off of TV. Was it a built-in feature? Did they sell blanks? Or maybe it was some kind of hack?

EDIT: According to Wikipedia they did have a built-in record feature and the Wiki page even shows an image of a blank tape.

You can just record over used magnetic tape, no? You don't necessarily need blanks.

But the player has to have the record function. Did it allow for that or did someone mod the hardware?
