 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. |

I hadn't come across this until today and it looks useful. It's by DarkElvenAngel. Github Here is the development thread. I think it would be a nice accessory for a certain little CP/M system. :) Mick Zilog Inside! nascom.info for Nascom & Gemini Preliminary MMBasic docs & my PCB designs |

I had some more fun. :) This PCB is a version of the VGA, SDcard & Audio Demo board in Chapter 3 of "Hardware Design With The RP2040". The I2S audio has been omitted, as have the PWM audio filters. There is no option to use 6-wire control of the SDcard. You will need a microUSB plug to USB-A female adapter for the keyboard connection. I haven't tested this at all. It might work and it might not. :) This is the same size, with the same fixings, as the RC2040. My idea is that the latter could be stacked on top of this on spacers and could get it's power from the serial port on here. Default mode is 256 colours. (It doesn't use all those outputs to get 65535 colours. It just happens to be a copy of the Pimorini board, which is the same circuit again, in case they are used in the future or for something else. These resistor networks are *NOT* supported by MMBasic).
