I wonder what that does?
That’s an 8 bit parallel access store, typically used for mainting values locally in registers in CPUs. The key is that you set the values you want, jump on the button, and they get ‘saved’. Awesome!
From there you can build integer units – crucially, all using a controlled store. Unlike the calculator level in LBP1, this allows you to create sequential instructions that operate on cycles – effectively a CPU, combined with indexable controlled store – aka ram. Plonk on top of that a grid of square lights…. aka pixels.
