Ralf (Ralf02, forum64.de) started a thread on the forum64 called Instandsetzung und Nachbau eines Kim-1 in March 2022.
99 pages further of designs and discussions in the thread, delivered a working KIM-1 that is closer to the original KIM-1 than any KIM-1 replica designed. A great achievement and a well deserved compliment to Ralf!
The work of Ralf is not limited to the KIM-1 replica itself. He also designed a KIM I/O module and a 1541 IEC/RAM/ROM module.
Noteworthy is the replica of the KIM-1 keypad.
