Vaporware historically includes stuff that never gets released officially, or was cancelled during the development process but was already advertised. One example of this was the Hellraiser game for the NES that would have pushed the capabilities of the console well beyond what it was ordinarily capable of because the cart included a Z80 CPU as a coprocessor. The Action Gamemaster (by Active Enterprises) in 1994. The Amiga Walker in 1996. Apple Interactive, which was a set-top box that ran OS 7, but it never went past the test type stage.
