i had heard that the Multi I/O was originally supposed to ship with a video port. I'm not sure if that meant a monochrome composite style port like the XEP80, and RGB like the ST or a TTL like the IBM, but I'm pretty certain it was originally going to include video--specifically 80 column video of some sort. I'm assuming getting rid of the feature was cost cutting measure as well.
Does anyone have additional information about the video port? Did any prototypes get released with video?
