Then what's the problem?
It wasn't me who came up with this.

It’s just that when a conflict between different pieces of hardware begins, that’s when they begin to
treat it. For example, by sending additional address signals to the device without changing the port values. And if two pieces of hardware hang on the same port (I don’t know which ports the GS was connected to), then what can you do? Toggle switch?

Well, when my GS conflicts with the cache, I will take action.
All the best.
Sincerely, Roman.
