I've discovered that Robert 'Bob' Leedom published another game called Baseball in the KIM user notes issue 16:
The "listing" of the game was pure HEX, no source file given. Typing in these listings is straight forward, but sadly the scan of the article is, well, miserable and to distinguish between 8 and B is sometimes impossible. So, as long as we have no additional informations, this game can not be reconstructed.
Some infos about the game: It fits in an unexpanded KIM-1, and is being played with the keypad and the LEDs
You can find the whole article here KIM User Notes 16 - Baseball
I've found a slight better copy of the KIM User Notes and checked every byte of my typed in HEX file. Five Bugs later I have something up and running.
There are two game modes:
- A one player batting pactice mode (default)
- A two player mode where one throws the ball (with the buttons 0-5) and one player has to hit; change the game mode by setting $002C to 1
The pitcher (in one player mode the computer) decides how the ball is thrown. The baseball then flies immediately to the Batter.
| Key | Pitch |
|---|---|
| 0 | slow Ball |
| 1 | fast Ball |
| 2 | up curve |
| 3 | down curve |
| 4 | riser |
| 5 | sinker |
The Batter has to time very carefully when to hit with the button B
I've played the 'batting training' and yould not find any errors.
There is the chance to add external switch to give you a better game experience. You can set the pitch on a multi position switch and include two buttons to throw and hit. (I need to try this soon)
