Notice. New forum software under development. It's going to miss a few functions and look a bit ugly for a while, but I'm working on it full time now as the old forum was too unstable. Couple days, all good. If you notice any issues, please contact me.

Hi Peter. I wanted to check as I may have misunderstood something on another thread. On the thread discussing hardware XON/XOFF for a terminal implementation, you say This thread appears to be discussing a hardware variants, or is a variant defined as somethinbg that introduces non-standard behaviour to usage in MM Basic? From what I can see above, the extra ports etc. are interfaced in standard ways (i2c etc) but are effectively giving extra headers. I think the models shown here are interesting, but I'd be cautious about writing for anything for an extra port I couldn't achieve with a bit of wiring out of the GPIO. Thanks for all the work and for "policing" the design to ensure consistency. elk1984 |

Hi This is not my post. But anyway the implementation of the mouse I have done on one of the i2c ports available on gpio, moreover the chip to handle mouse is optional, You can insert it to dip socket or not, If You dont there will be no difference to original. This is still design experiments how it will end depends only from people like You. |

As stated This board with the extra chip is exactly the same as my development machine with the Hobbytronic board plugged into pins 27 and 28 of the I/O connector just a little bit tidier |

Absolutely, all of the suggestions on the thread are looking great. @matherp - I wanted to check what is likely to remain supported as a CMM 2+++, and what's considered a cul-de-sac. Looks like if it extends stock behaviour - it's OK; changing stock behaviour (like rewiring the pin out of anything) isn't. Great work @siwypiotr. I'm really looking forward to seeing the next version of the board and will ready to put an order in as soon as it's ready. What are the dimensions of the new case?

I will let everyone know that it is done. The case dimensions are: 165x255x40mm |

Here is pinout of the DB9 joystick port, I have used one of the forum users suggestions: https://www.thebackshed.com/forum/ViewTopic_mobile.php?TID=12282&P=3 DB9 FUNC -> GPIO 1 UP -> 35 2 DOWN ->36 3 LEFT -> 38 4 RIGHT -> 40 5 - 6 BUT A ->32 7 +5v 8 GND 9 BUT B ->33 If You have any questions please ask, I will be very happy to answer. Someone mentioned that pin 40 can reset the computer's stored options if its connected to ground on bootup, so we were going with pin 29 instead for digital right. Not sure if that's something you might change for a future version, it would be cool to have more things that can use the same pins. |

I do not think that this can be issue to anyone, by the way pin 29 is not 5v tolerant. |

Orders can be placed via email: biuro@pslabs.pl I like the prototyping section on this one. He is considering adding one of the mouse options from forums to his design but if you get one now, you or he could just add the circuitry for it on the prototype section and use the SCART cut out to add the port. he could maybe sell a small PCB and wiring instructions. I think this is the best part of the design. The rest is very nice too. It is not a problem to add mouse support on next version. I can do it by adding additional STM microcontroller with USB support and send data to main processor using i2c or other protocol. But I do not want to create additional standard, creators of the firmware have to agree how it should be done and I will follow their standard. |

have you seen this thread (https://www.thebackshed.com/forum/ViewTopic.php?FID=16&TID=12954 )? Is this an option to Hobbytroinic chip? for your design. That would be WAY less expensive and also put a Arduino on the system with many more options. A full NANO board can be had for less than $2, so just the chip should be much less. Just asking. I like the idea of a open source flexible option like this. Thank. Hi I have added place to install HobbyElectronic chip, there is dip socket, You just buy this chip and install it: https://www.hobbytronics.co.uk/usb-host-dip?keyword=mouse Arduino is not good idea for the mouse as it will work only with PS2 mouse and they are hard to find. If You want to have arduino for whatever reason You can use the internal header to install it (extension boards are coming soon) I meanwhile I will also work on my own USB mouse chip when done it will be open source.

Very nice. Thanks for the feedback. I am hoping for the arduino version because I will cost me almost nothing as I have most of the parts including several PS2 mice. I just ordered a Nano from FleaBay for $1.50 pulse some work and I got me a mouse. I like the idea of yours or any good open source solution as that keeps the development in the community and not out to propaiatary systems. |

Dear Maximite users New version of Maximite 2 have arrived. USB mouse host controller dip socket is added as well as additional USB port for connecting mouse. Chip can be bought separately from: https://www.hobbytronics.co.uk/usb-host-dip Functionality however is not tested (my hobby chip have not arrived) however I do not see any problem for it to work. There are still couple units left if You are interested in purchase. |

I just got the shipping notice from CircuitGizmos for my RetroMax system. I am looking forward to having two built-in Nunchuk/Controller ports, and also room to add the HobbyTronic USB Mouse interface. -Bill |

-Bill I did too! Is the USB mouse interface just a matter of plugging in a chip? |

I did too! Is the USB mouse interface just a matter of plugging in a chip? The CircuitGizmos RetroMax is a CMM2 compatible device. Please see: https://circuitgizmos.com/RetroMax-CGs-Color-Maximite-2-p241231864 There are two different products from two different companies that people are assuming to have the same features.

It is getting a little confusing with the different variants, but I ordered teh RetroMax from you. I was just commenting on the other poster's thoughts of adding a USB mouse. |

Yes, there are multiple similar products with somewhat different feature sets. I ordered mine from CircuitGizmos because I have already purchased a standard CMM2 from them and I like their service. I have the HobbyTronic mini-board for supporting a USB mouse. But no, there is more to it than just plugging in a chip. You have to connect the control lines to one of the I2C circuits; this involves connecting power, ground, clock, and data lines. Also there is some software work needed in order to use the mouse with an application. I have not yet dug into all the details but I will post a report if and when I get it working. -Bill |
