46 byte hard drive

its 26x17x44 in size which is not including the busing in the front, the way it functions is similar to stack memory. it has a rotate clock wise and a rotate counter clock wise and a read and write. the two rotations could be a push and pop in that sense. It uses xor logic to treat the memory as d-flip flops in which case it has to swap a 0 and 1 block with pistons. Yes this is is a piston feed tape with a write function so pretty weird but fun to use XD
