I assemble Apple 1 replica using the maximum USSR components (In the future, 2513 will be replaced by РФ2, MK4096 will be replaced by РУ4, etc).
At the moment I am debugging a video terminal.
There are two problems:
1. The image on the display flashes and moves. It looks like a problem in the monitor used, apparently does not support vertical synchronization of 60 hertz.
Already ordered a new monitor, I hope this will help
2. @_ disappear on the screen within a couple of seconds (are the registers cleared?)
If I remove all 2504, I see @@ and they do not disappear.
Not yet figured out what the problem is.
Has anyone had a similar problem?

Some times if I turn on/off my AI replica several times, "@_" replaced by "@#". https://drive.google.com/file/d/1-AVchyRI3lvSLTXYuTsxsa6840VzftZc/view?usp=sharing
