  • Excellent work, the conventional keyboard is working but all the special keys that are behind the transistors and diodes do not have any behavior in the spectrum, I tested with the ROM 128k, 48k and 3e without response. Can you give me a tip?

    Using the keyboard test and pressing up, down, left and right I get these readings from the images

  • HI, I made the Mechtrum that used your older keyboard and have looked for a + style that will work with ESPectrums and PICO spectrums, I tried a few of the others and they never worked because I think the new esp and pico are not providing enough power. Do you think this new keyboard could work and is that a dedicated power and ground supply for the extra logic needed to do the switching ?

    Hi,
    This keyboard has extra 2 wires (red and black in picture) for connect to 5V and GND, I think it should work with those board.

    Thanks for the quick reply, I have shared my thin connector PCB for the keyboards if that is helpful to you.
