MUMIO is an open specification, allowing anyone to design their own device controlled by a ZX Spectrum computer. The number of possible MUMIO devices is unlimited. You can create your own device yourself.
When you’ve explored all the existing MUMIO modules, take the next step: create your own electronic module – design the circuit, have the PCB made, receive it, solder the components, and get it running!
Once the module is ready and you want to share it, send me the information. I will assign it device number #xx and feature it on this page.
