Another KIM-1 game by Robert Leedom.
Thanks to Nils for providing this material, and letting Robert Leedom dig up even more material!
Baseball for the KIM-1
(text by Nils)
Robert ‘Bob’ Leedom published another game called Baseball in the KIM user notes issue 16:
The “listing” of the game is pure HEX, no source file given in the Usernotes. But Bob has provided that now!
Some information 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 http://retro.hansotten.nl/uploads/files/6502%20user%20notes%2016.pdf
– Bob Leedom has digged up much more information than published, like source (handwritten, 16 pages), readable hex dump, photos of the hand controller described next. All part of the downloadable archive.
How to play
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 Batter has to time very carefully when to hit with the button B
Nils has played the ‘batting training’ and could 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.
Bob sent pictures of his (back in ’79) self build external controls for KIM-1 Baseball
Now this is oldschool. Do you see the self printed circuit board? It fits directly in the KIM-1 extension port!
Special thanks to Bob Leedom, who dug in his basement in the search for all the missing documents, scanning and sending it
