Here's the first official announcement of my new upcoming game for the Colour Maximite... Donut Dilemma! This is a game I originally created for the TRS-80 Model 1 back in 1984, then recreated for the Radio Shack/Tandy Colour Computer in 1986 and now finally for the Colour Maximite in 2013. It's 95% complete at this stage and undergoing testing, bug searching and the completion of a few minor routines. I have started a website for my Maximite creations and you can see pictures and video here. The program will also be downloadable from here when complete. Geoff has been working with me to make some improvements to MMBASIC to facilitate better keyboard control by utilizing a new command, KEYDOWN which provides a more realtime scan of the keys without the inherant key repeat and delay obstacles that have plagued games with fast controls in the past and making them almost "joystick like" for those that are use to the keyboard arrow. Still, you can't beat a good old joystick and it, as did MaxMan, supports an Atari style joystick using Fabrice Muller's joystick connections and the Nintendo NunChuk. There will be an opportunity for someone to distribute joystick interface adaptors for the Maximite and would make a good Silicon Chip article! Those of you who haven't hooked up sound to your Colour Maximite will have a reason to do so since Donut Dilemma uses the PLAYMOD command to produce realistic sounds. Anyway, enough ranting. On to the website!! http://www.members.optusnet.com.au/nickma/MaximiteProjects/ Nick |

Thanks to "djuqa", we can now access my site using... www.maximite.net.au instead of the long laborious one I had before. Thanks David! Greatly appreciated! Nick |

That looks familiar! From memory, I think the NewDOS/80 disk I've got kicking around somewhere for my TRS80 Model 4P actually has Donut Dilemma on it :D Capacitance is futile - roll on 2012! |

Just curious how many people have a joystick attached to their Maximites? And which one? Atari or Nintendo Nunchuk? Nick |

I use the Atari one. |

Good to have the schematic for anyone to build their own. I'm putting together a small Joystick interface design based on this schematic. Hopefully, someone can design a professional version of this board or maybe the entire product complete to sell so everyone can enjoy the vastly improved control that a real joystick provides. Nick |

The schematic looks to be for a "button" type joystick. Has anyone done a proportional one using linear pots and adc? David M. |

Is there an analog game? How about Pong? I'll suggest I/O 9 and I/O 10 as analog inputs for an analog joystick. Micromites and Maximites! - Beginning Maximite |

The Atari joystick standard (9 pin D connector) supports 4 digital inputs for up,down,left,right switches... 1 digital fire button (Amiga revision supports 2) and 2 analogue inputs for X/Y axis (analogu joystick). An Atari interface for the Maximite should support all these. Nick |

I attach/remove/re-attach regularly and use the Nunchuck. They're so cheap on e-Bay ($3 or 4) and zero postage ex Hong Kong. Greg |

My game supports Atari Joystick and Nunchuk. My best scores are had with the Atari joystick. It just seems more intuitive than the Nunchuk. Nick |

This pic is from Wikipedia. I assume that these are the right connections for an Atari joystick.

That's it. the famous 9-pin "D" Atari joystick!  |

I'm not sure if it was Atari that "Invented" that standard, or it was just one they adopted. In any case, the Commodore 64's also have exactly the same joystick port, and others of the time such as the ZX Spectrum and Amstrad I think also had the same joystick connections. The old switch-based Atari joystick was remarkably good for game play of the day. I still have my red and black "Turbo II" joystick. This one has microswitches and an autofire switch for games where you would break your finger pressing and releasing the fire button all the time! (such as Track And Field or Fort Apocalypse) The very first joystick we had used a tinned PCB for the contacts, and a star-shaped metal thing in the middle, and when you moved the joystick in any one direction, you would force the metal thing to bend down and touch the PCB pad. It worked OK, but broke quite easily over time due to metal fatigue. 
Smoke makes things work. When the smoke gets out, it stops! |

Atari invented that interface for their range of video game consoles LONG before the computer makers embraced it. If you want a Bulletproof joystick several online vendors sell Arcade quality joysticks that can easily be setup for that interface. With solid metal shafts and proper heavy duty micro switches.
