Nils a.k.a. netzherpes typed in a number of KIM-1 programs to run on his PAL-1, the KIM-1 compatible clone.
Not only does he types them in in assembler, some even by contacting the original author!, tests the programs and also provides source and ready to run binaries or papertapes.
And he draws nice looking cover images!
On his github page he has the most recent versions and adds new programs regularly.
Also checkout his blog!
Here a summary of the programs:

You have 20 shots to detect a 3×1 ship on a 8×8 grid. The ship can be aligned horizontal, vertical or diagonal.
How to play: Enter the coordinated and fire (Button F). If you hit the ship, the mostright counter will jump to 01.
If you hit all 3 coordinates of the ship, you won, the display will show “dEAd” and the number of shots used.

This is a walkthrough of one of the most amazing computer games in history.
KIMventure is a (colossal cave like) adventure game for the KIM-1 that fits in only 1 (ONE) KB of RAM. It offers 24 room to explore with a lot of traps and riddles to solve. It was programmed in 1979 by Robert Leedom with pen and paper (no assembler etc.)

A Dutch company, producer of many 6502 and more industrial hardware, BEM was the name one of their product lines.
Brutech Electronics Microsytems – B.E.M
Gebroeders Bruyn, Vinkeveen. Small company, custom made electronics and standard microprocessor boards and systems aimed at industry and hobbyist.
During my years with Radio Bulletin we often worked with Brutech, and I visisted their office/manufacturing plant in Vinkeveen several times. The BEM-bus became the standard bus for expansion at Radio Bulletin after the first BEM-1 card was connected to the KIM-1 by Dick de Boer. Brutech specialized in the beginning on the KIM-1/VIM/SYM-1 expansion cards, later on they made their own CPU cards and besides the 6502 CPUs like the 6809 were available.

MAiS, a system for airtraffic control, developed around the BEM SBCD4 and a custom card.
As editors of the magazine Radio Bulletin we had many conversations with them and wrote articles about their products.
For the KIM-1 and SYM-1 they had many products, some based on the so called BEM bus (DIN 31 pin connector), some as addons to the 22/44 edge connector of the KIM-1.
I stilll own this 4K RAM card:

Known by advertisments in the KIM-1/User Notes.
KIM-1, AIM-65, SYM-1 and other 6502/65C02/65C816 related books.
A mix of English, German and Dutch books.
On my bookshelf I have quite a collection of books on the 6502 family.
Note that manuals and books that come with systems are shown on the pages of the corresponding system!
Micro Technology Unlimited produced a lot of hardware and software for the KIM-1, SYM-1, AIM 65 and more.
The company is still in business, now sells Karaoke software.
On these pages I have collected what is known about MTU and the products for the KIM-1 (and the MTU-130/140).
