storage for computer?

[36564176]

i think im gonna try and make a computer in factorio, and i stumbled across this issue. how do i make some kind of storage that works like a hard drive (doesnt lose data when its off)?

Some Flip-flops?

you can wire a arithmetic combinator to itself with 'each + 0' output 'each' and it becomes a memory cell for any signals you put into it.

will it keep its data if it didnt get power though? i just need to know a method for non volatile storage

Just a thought....considdering you want it to store info whilst having no power; ever thought about using something mundane like Coal to serve as "bytes"?

Hook up a chest to Nixie tubes (mod) and let it read the content to display it as a number on the tubes. Then all you have to do is hook up a storage and maybe 2 or more inserters to peddle coal/copper between the storage and your "harddrive" chest.

Just my quick thought on the matter

yes it seems to save it.

You can alternatively use a decider combi pair to make an addressable memory cell that can be set / cleared by a single control signal as needed.

The arithmetic version stores data fine, but needs the inverse of each signal to be pushed in to clear each one out. 'Tis a bugger to wipe easily & cleanly.

Combinators remember their last state when becoming unpowered, which is a huge advantage with memory cells.
However: low-power can often break tick-based circuitry as parts can go out of sync, even with a clock signal, so make sure to include a manual reset switch somewhere.
