The replica is yet another implementation of the idea from my Dutch friend Ruud Baltissen: Build a KIM-1 with 6532s replacing the 6530-002/003.
What makes this replica special is:
- It is a KIM-1, with everything the KIM-1 has: two 6532, audio, 1K RAM, 6530-002 and 6530-003 ROM, exactly the same logic for TTY and audio, application and extension connector.
- The layout is in size and layout nearly equal to the KIM-1, it looks as close as possible as the original
- The extra ROM is hidden on the back of the PCB
- The PCB traces are not straight with sharp corners, but are bended like the hand layed out KIM-1 PCB
The keyboard is the best replica of the KIM-1 keyboard ever seen, see the KIM-1 replica keyboard page for details.
Ralf made available the gerbers of the Nachbau KIM-1 PCB and wrote a (in German) construction guide.
Here are the available downloads:

Bare PCBs (thanks Micha!), not the latest, but will give an operational KIM-1
