Hey! The Commodore/AMIGA logo font on that prototype case with the green power button is really different and cool! As is the very early pre-Commodore stylized "A" logo key near the enter key on the developer system. That stylized A key uses the same font as the earliest Amiga logo (from when Amiga was still its own company making joysticks to fund R&D).
Neat to see the "what could have been" graphic design elements of these early Amigas.
