Spectrum Computing

Hello there

Im owner of a 128k +2A Grey.

I dissolder a pad due to higt temperature.
Can someone help me, where that pin in photo connects to?

Thank you very much

Hi

Im Pedro, from Portugal. I have a 128k +A grey, bough recently. I never add a Spectrum,so i though this was the time.
It has some issues, but that stays for later.

Thanks all
