A 40 year old HP 5060A is smaller than a small refrigerator.

I challenge Anil to tell us what fridge he's thinking of which is the 
size of an Efratom FRS. (Although you could easily make one using a 
peltier cooler, that's clearly not what he meant to imply.)

The article and headline hype a reduction in size, but there's no 
detail about that, just that it "could be used in space-based 
experiments," and we already have atomic clocks in space.

What "magazine" was this from?

(Anil obviously missed the real significance, which is a potential 
increase in accuracy, not a decrease in size)
