TRS-80 Disk/Video Interface

Hi All, Pardon my stupid question, I know nothing about Trash 80's. OK, the question of the day is what is this? It looks like you are supposed to plug a ribbon cable into the bottom, and connect it to a computer. I've been looking for TRS-80 stuff to add to my collection, so far I've only got a CoCo2, so when I saw this for $8 I grabbed it. It's got one 5 1/4" drive in it, and a spot to stick another. On the back is a plug for TV, and another for a monitor (they both look the same). Which TRS-80 was this for? Thanks, Zane | Zane H.
