Best I can tell, the addons package for Opalvision was named the Opalvision Video Processor. This is the label added to the box containing a beta unit that I have.
This consisted of an Opalvision, Roaster chip for the Opalvision boards empty chip socket, the Framebuffer card that attaches to the Opalvision, a fan to cool them that blows through a hole on the daughtercard over the roaster chip (I think, been a long time since I've taken that out of the box).
In truth, Vaporware should be limited to items actually announced as being prepared for sale to consumers. The Opalvision Video Processor definately qualifies. I think they were even taking orders for this before it slipped beneath the waves. Internal prototypes and devemopment systems, though we might wish they had been completed and sold, are not technically vapor.
There had to be smoke for there to be vapor.
But all in all, an interesting and informative list.
