The core routine of the disassembler is the well-known Steve Wozniak/Allen Baum 1976 article A 6502 Disassembler from Apple
The program is a TTY program. I build it with the then current hardware and software of my KIM-1:

• 32K RAM from $2000
• Video terminal uppercase 24×32 on the KIM TTY serial in/output
• A parallel ASCII keyboard connected to the second 6532 RIOT port
• A serial connected, at 9600 baud, Heathkit H14 matrix printer
• Dual audio cassette records under motor control
• MICRO ADE assembler/Editor, extended and with video TTY as output, parallel keyboard as input and could print at the H14 printer

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.
