@lucky1 what is function "enhancer" for and what is it doing? I found no description, when I was searching. Is there any influence on the XL-devices?

That is mainly used for old V1 and V2 STM32F4 discovery shields where the LS123 circuit is missing.

Later the LS123 was added to improve/enhance sync . On later models this menu item should not be changed

except on 128x16 boards where I reused it for the different sync methods of ealier machines.

I just received one of those boards for analysis and now I know what the problem is.

The socket for the Z80 CPU is badly soldered.
