So am I, it's a scan of the cover, but I'm not sure if it's it's real or composited. The "smoke testing" protocases for the SE from the same development period make me think it might be real, but the lack of detail for the plug in the second FDD slot makes me think composite. There is also the lack of retaining/positioning tabs for the NuBus cards to be considered, but they wouldn't be necessary for airflow tests or necessarily soft-tooled in a very early prototype. The apparent lack of thickness of the case seen on the corners has me leaning toward composite.

But either way it's definitely on my gottahaveit list for the pet IIfx! :approve:
