DO NOT USE MOBILE / CGNAT DEVICES WHERE THE IP CHANGES CONSTANTLY!
At this time, it is unfortunately not possible to whitelist users when your IP changes constantly.
You may inadvertently get banned because a previous attack may have used the IP you are now on.
So I suggest people only use fixed IP address devices until I can think of a solution for this problem!

Thanks again for the help.
Great! I'll be recapping a few SC1224s in the coming months so this will help me too.

Hi all,
I have an SC1224 and I am looking to do the adjustment on the vertical alignment (vertical centre) as it's too low currently, but I cannot see R626 on the PCB or anywhere else...

It's a Goldstar with a Hitachi screen, and it has Atari printed on the bezel, but not on a badge of any type. I wondered if anyone can help me locate this?

Thanks,
Paul

Those old monitors can be tricky to recalibrate after replacing capacitors. Nice work on figuring out the exact adjustments needed.

R626 is behind the on/off switch
