My KIM-1 came as an Rockwell OEM kit. The Rev F board is made by Commodore MOS Technology, the packaging and manuals are the original MOS Technology books, but Rockwell branded.

The logo on the KIM-1 is covered with a sticker, of course to have the Rockwell logo on the board. But some one was so clever to add essential information and addresses of the KIM-1 monitor.

Guido Lehwalder gave me photos of his KIM-1 Rev A. Thanks!
Note the different colors of components.

I added these to the KIM-1 Revisions page.

Tor-Eirik Bakke Lunde a.k.a TEBL created several computer systems with detailed documentation.

The RC-ONE is a KIM-1 clone, inspired by the design by Ruud Baltissen, which can be built in a compact to much expanded format.

TEBL separated functionality into separate boards so that each version would cost only around 5$ per piece instead. It means it’s no longer a single board computer, but if it means more people can build it as a fun project then that’s a plus in my book. The main setup does not include the additional 15 I/O lines due to space requirements, but you can add those back to the system by including the 65K Expansion (in addition to the backplane module) if you want to. If you just want to play around with the system and try your hand at machine language coding, you can get started with the CPU board, UI board and a keypad module.

The whole design is documented on TEBLs github page, from circuit diagrams to PCB design.

The manual is an excellent guide to the system, read that first!

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.

On the forum Mikrocontroller.net I found a thread dedicated to a KIM-1 replica with a twist.
Author is Manfred Langemann (manni), this page is published with his permission.
Read here about the KIM computer which has the following features:

• A complete 6502 Integrated Development Environment (IDE) for writing assembler source code, including editor, assembler, debugger and EEPROM programmer, see screenshot above.
• The hardware comes with a 6502 micro-controller, 8 KByte EEPROM, 32 KByte RAM and an I/O interface based on an Intel 8255 PPI (Programmable Peripheral Interface), offering three 8-bit ports. The audio tape interface is realised by an NE565 PLL and the RS232 serial interface is based on a MAX232 IC
