Note that there is this problem (solved at Rev 1114):Fizic_S wrote:I posted a Nibbler project in which ROM/RAM is used in read and write modes. In the new version, these subcircuits did not work. After selecting the "Asynchronous" property in the ROM, the subcircuits worked correctly. Nibbler does not work with any settings of this property. Therefore, it is important that the ROM component has this property set by default

after recording a number in memory, there is a low voltage level at the output (screenshot 3)
So the synchronous/asynchronous can't be tested until the next upload with this problem solved.
That's the idea.Fizic_S wrote:it is necessary that the operating modes of ROM / RAM are standardized and not changed in the future.
In theory old circuits should work without changes.
And now there is a new mode of operation for RAM/ROM.
