In addition to being an assembly language programmer, I am also an electronics engineer/technician (with probably "similar level of experience", or even more), and therefore, with knowledge of both areas, I can think of hundreds of different ways of being able to build something that generates random numbers, and of high quality (for example, based on white noise generators, which are the thermal noise of semiconductors, try to predict this with supercomputers). Therefore, I don't think this is ...
