[Coco] 6847T1 Datasheet

[CoCoList for Color Computer Enthusiasts]

What I believe to be an early, unreleased version of the 6847T1 is in the Deluxe CoCo. It shows significant missing lines when it goes into lowercase mode, which makes me think that it’s a prototype.

As soon as John Linville ships it back to me, I’ll take a look and get the exact part number on the chip. :)
