That EN76 article is great.

I particularly like the comparison between binary-weighted resistors for uniform distribution versus equal resistors for gaussian distribution. I wrote an application to graph and explore the transfer function of different bit weightings, but I didn’t think to look at distribution (probably because I wasn’t dealing with random inputs and outputs).

As it happens, i just found an ancient build attempt of the EN76 digital noise source that Jay referred to...  it didn't work at the time - it was in the (large) "pile of sad failed projects") - but that's the direction to go.
