That is pretty cool. So now I know if you don't mind I am going to pick your
brain a bit: Were there two revisions of the 5322? 

I ask because I have two 5322s and while very similar they differ in at
least two areas: The older model seems to have a linear PSU and socketted
chips vs. the newer one with switching PSU and soldered in chips. Just
wondering. Thanks.
