I have nearly the same set on my desk, was a freebie otherwise I would not have it. Works fine off AC, though the battery contacts are eaten up. I also scrapped another 5" color set that had cought fire(!) for the crt. I am not sure but I would be willing to bet that this is the smallest color crt made. Have you noticed looking close that it is not full resolution? I kept wanting the focus tighter, then noticed the size of the pixels. I guess they just couldn't make the phospor bars any smaller back then and keep the cost low. Today's computer crts have tighter pixal layout but of course with LCD tv's who would want to. Here is an up close and personal of that 5" color crt.
