C64 Expansion Port Adapter
This is a very small 90° Expansion Port Adapter for the Commodore 64.
It was designed because of public demand at the Forum64.de.

The goal was to spare as much space as possible behind the C64 despite a plugged in expansion port card.
Meanwhile the third revision with minor improvements was built.
The Adapter is tested with the U1541, the Turbo Chameleon 64 and other cards.
The first version. A bit rough at the edges.
The second version. Shorter and with rounded edges.
The final version.
