Description
Small binary cobinational RAM that does not use observers/pistons/1.21 items or anything of sort. MCHPRS compatible.
Size: 2x2x7 blocks per bit (stackeable + can be flipped to merge outputs of different modules)
In theory possible to get to 6 blocks long due to large amount of air space where the toches are but... probably not too doable tbh
Write/Read are on the same glass tower, but still work separately and don't affect one another. Reading and writing to the same byte at the same time is not possible, only one at a time.
