Wrong guide for memory cell

Post by gGeorg »

https://wiki.factorio.com/Tutorial:Comb ... ial#Memory
scroll down to Positive cell
Picture do not work. It is wrong setting :
Aritmetic combinator is :
Signal O + value 3
correct is:
Signal O + Signal 3

Naming convention of signals is unfortunate. On top, description could be better as cell does something else.
Output of the memory cell are 2 mutually exclusive signals.
In case input signal I > 0 then signal I is passed to the other side.
In case input signal I is interrupted, then signal M is passed instead as a memory of previous input value.
When input signal I is interrupted, it takes 2 ticks to switch to memory signal M.
In case input I signal lasts only one tick then memory cell start to cycle 2 previous values, tick by tick. Indefinitely.
Switching is seamless, e.g. no ticks with empty signal.

Thank you for finding this and pointing it out. It would be great if you could change the description of the cell on the page to your proposal, I already fixed the image.
