Aart Bik has started to publish a series if tutorials on programming the (Micro-)KIM on his blog.
Here you will find the collection of publications by the KIM Gebruikersclub, called the KIM Kenner, later 6502 Kenner and at last uPKENNER.
Note that the PDF’s here are in black and white, right order and orientation, from corrected images, without irrelevant pages such as memberlist and non-6502 ads, missing pages added, lower quality rescanned and doubles removed. Contents added by hand!
The August 1975 Cross Assembler manual MOS Technology has been added to the KIM-1 page.
