 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. |

This idea was sparked off by a comment from Vegipete. Cases were being discussed and he came up with this in this post. ( AliExpress link ). I thought, why not?  I incorporated the RP2040-Zero USB-PS2 converter this time, purely because I wanted the space that's available underneath it. This is the one suggested by Hawk in this post. It's possible to use a second PCB in the top slot of the case, but you have to be careful because of component heights. I've come up with a design that duplicates the GPIO port using a second RP2040-Zero connected via the system I2C bus. That takes up the front half of the PCB. I don't have a use for the rear half yet, but height is very restricted. Mick Zilog Inside! nascom.info for Nascom & Gemini Preliminary MMBasic docs & my PCB designs |
