I downloaded your mod but did not figure out how to use it.
Can you add a more detailed description? It is possible to add an example of use.

I'm in the same boat.

Well some tinkering with this mod/machine. If you wire up a constant combinator and emit a signal of -1 value to the Reader channel/signal the mod creates/adds to the game, it does eject the disk. I'll assume the write channel -1 clears the inventory of the disk as per the description. But as for loading items into the storage and observing it's inventory contents, still no luck.

Okay lol I think I figured this thing out with further tinkering. So if you into said constant combinator and assign output signals such as the DISK Writer, set it's value to 1, then set a signal for some other in-game item such as Shotgun shells or Plastic, then turn off those signals and then output a DISK Reader channel of value 1, you should see those consumable item signals and values as you now mouse over the embedded constant combinator "Control Node" of the DISK Reader machine.

At this point I seriously doubt there's anymore to it. Like as far as de-materializing and re-materializing items for storage. I could be wrong, but I believe that's it for now.

Thank you for explanation. Now i see how they work: removable memory for circuit signals. Sometimes may be useful.

I misunderstood the purpose of the mod for its description. There is written "Removable storage for combinator circuits" and I thought that somehow you can write not the circuit signals but the circuit scheme (blueprint or so on) itself on this disc. To send the input signals to the reader, it will process them and output the output signals depending on the circuit scheme written in the memory card.

Well you send signals to a Writer channel # greater than 0, but then when you emit the same Reader channel # greater than 0 it reads back out the signals that were input. An interesting proof of concept I suppose. I'm trying to research what it'll take to create Applied Energistics from FTB for Factorio. Storing items/inventory to an entity such as what the "Modular Storage" mod does is pretty simplistic. Now I'm researching howto store a custom model (relative to C# or any Object Oriented Programming Model) per entity such that additional mod information can be associated to an entity. For example AE in FTB you could set a priority to every device on the ME network. That is something the logistic systems of Factorio do lack. If blue chips are limited supply and I request some on my logistics slots, the bots might prioritize my request over the Requester chests, it may not, there is no certainty. I do Senior level .NET programming, among T-SQL and other technologies for my day job.

Applied Energistics in factorio it sounds cool.

You and now can set a priority in the logistics network, depending on the amount of any material. With the help of the circuit network.

Here I set the priority for the delivery of iron ore, depending on the availability of the specified number of steel plates. You can also do the opposite. Set the priority for the delivery of iron ore if this iron ore is more than the specified quantity.

Now with the help of some mods and circuit network, you can build incredibly flexible systems.
I advise you to pay attention to these mods:

Another thing is that the control circuits of such systems are very cumbersome.

So, first of all, I don't check mod portal discussion at all - github issues woudl be a much better way to reach me.

Secondly, this is a data storage mod. It's like an SD card. Where'd you get this item spawning nonsense? :D

You send pulses of data+writeaddress and it'll store it, and give the data back when you send a pulse of readaddress. It's meant to replace long strips of constant combinator based ROMs, but with a card you can remove to swap out "programs", for computer builders or musicbox makers.

no idea what these guys were talking about, but this is just what I was looking for! Thanks so much!
