Reset button

Post by nama »

I have an extra key on my full travel keyboard that I want to use as a reset button. I'm so sick of having to always pull the power. Can anyone tell me how to wire it up so I can get a safe reset?

Thanks
Phil

Hi NaMa,

The Reset button is wirred on the C5 capacitor (hot boot).
It pull down the z80 reset pin.
Just short-cut the capacitor (ground+and the other C5 pin), to reset the Zx81.
Have Fun.
