And yeah it was kinda sloppily written but i hope this helps abit :)
and a way to choose which register you want to modify now right? so you'd need a addressor (lets say a 4bit number, so another 4 wires) which converts a binary number into piston motion so it can push each register in the way of some beams or something, to highlight a specific register (lbphacker did some and they are linked in my microprocessors something save). When you do the electronics for the interface you will have a RAM memory ready for use)
but basically you first need to be able to store 1 bit and read its state. When you do such a thing, copy paste 4 of then and now you have a 4 bit register)) you can now store (and use!) a 4 bit number. But if you want to store multiple numbers you'd need multiple registers, so copy paste that register idk 16 times and make an interface, so you can write/read/clear a specific register. Basically you'd need 4 "wires" for the data input, 4 bits (wires) for the data output
idk if i really can tbh sorry
hey novice can u teach how to make ram rom and other like this?
