 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. |

Pardon my ignorance I have not not much experience of MM basic. There is not much choice these days when it comes to PS2 keyboards. I have few questions. 1)From MM basic (no C functions or PIO jiggery pokery) is it possible to produce a PS2 keyboard with all of the keys pertinent to MM basic. 2)Would it be possible to enable redefining a keys output e.g. Shift/2 = (") UK keyboard. Shift/2 = (@) US keyboard. 3)Has someone already done it. I know MM basic has it's limits this may be it. I though it might be of use for producing dedicated keypads for specialist functions, or for game pads to avoid over enthusiastic gamers beating the life out of their regular PS2 keyboard . There are a number of projects that require a scaled down PS2 keyboard from the retro computer scene. Just a thought. |

I can't think of a way of doing it reliably with current functionality other than a csub. However, I have an idea.... watch this space |

Thanks for the replies I thought it would be tricky. The most of the PS2 keyboards I have tend to be rather large, a USB PS2 converter with a Pico would enable the use of some of the smaller USB units. I wanted to make a small semi-portable computer just for the novelty value. I will be watching this space! |

My latest game platform, GAP1, uses a PGA2350, HDMI and a PS2 keyboard and mouse (if you have a Y adapter). I decided to leave off USB this time. :) More later. I got some PCBs today. Mick Zilog Inside! nascom.info for Nascom & Gemini Preliminary MMBasic docs & my PCB designs |
