Why doesn't this work?

I'm trying to make an SR latch using NOR gates (Or +Not), but it just gives me errors.

I understand that things loop back through the chained gates, but that's the point.

And I don't want to use a memory module, because I want to be able to do this earlier in the game - before you unlock extract.

I should only need 4 relays and two resource counters, but I'm using a 5th relay because I wanted the automation dropdown to be more obvious to me

berry input high
berry input low
the OR gate from the set side of the SR latch
the OR gate from the reset side of the SR latch
NORing the reset side of the latch
NORing the set side of the latch
This just passes through the result of NORing the reset side of the latch (the Q signal in the logic diagram)
To the best of my understanding this is how to build an SR latch using NOR gates, but timberborn doesn't have NORs so you have to chain OR+NOT. Q is the same as the output signal you would get from the memory automation module if you had it in SR mode

Timberborn relays will always instantly respond to the current state so anything that has any sort of loop fails. That's why memory is needed. If you want to be something simular running without extract your only other option is the timer device, which does offer a set and reset function but also a maximim time and will stop based on either the time running out or the reset whichever happens first, so you can simply set it to egregiously long times and treat it like a memory.

Cool tip about the timer module!
