Updates to KIM-1, AIM 65 and SYM-1 pages

With the help of users on the German Classic Computing forum I ahve added many manuals and magazines in german about those systems:

AIM 65 PC100 manuals
MICROMAG magazines
KIM-1 manuals in German

I also added books on the 6502 in general and on the KIM-1, SYM-1 and AIM 65 to the Books section.

Reading old magazines is always fun, from the period 1976 to 198x magazines were filled with articles on the 6502, the KIM-1 and other SBC’s.

German, Dutch and English magazine articles extracted here.
Kilobaud, Byte, Dr Dobbs and of course the dedicated 6502 User Notes, MICRO Journal and Compute are valuable sources, but look at the many magazines on this page!

KIM-1 programs by Nils

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.)
