    Default Early A500 Hi-tek / NMB "space invader" keyboard - in need of repair

    Hi folks,

    Up for sale today, an early A500 Hi-tek / NMB "space invader" mechanical keyboard ("C=" key in place of the left "A" key) in need of repair.

    First the good news:

    It's complete, it looks great and it feels great. Nothing feels mechanically broken and it has zero yellowing. I suspect it would be much nicer to type on than the common Mitsumi keyboard. If I knew how to fix it I'd be keeping it!

    Now the bad news:

    It doesn't work. When plugged in it usually stops the Amiga from booting. The only thing that responds is reset. Occasionally the system will get to the KS / insert disk logo and if then booted into WB or systest, etc none of the keys register. The caps lock key is usually stuck off, occasionally stuck on. It does not flash to indicate a failure (or toggle when pressed).

    There are two visible signs of damage:

    - Both LEDs have broken solder joints and one of the traces for the floppy LED has lifted and will need repairing.
    - There's a scratched trace along the bottom of the PCB though tests with a multimeter show continuity is still OK.

    The rest of the PCB looks fine to me. Obviously it may or may not be damaged beyond that. I suspect the controller or one of the other ICs is dead. I don't own a soldering iron or have anything but very basic electronics knowledge and have no way to test this further. I have not attempted to disassemble the keys or even clean the keyboard as I understand the key mechanisms are easy to damage.

    Asking 25 excluding postage and fees. Paypal F&F preferred.
