Re: J5 definition

My bad.  I should have noticed the uart is U3 on the daughtercard, not U5.  
Sorry.

Is there a "U1, U2, U3" nomenclature for the modem card somewhere on the 
wiki?  I dug around but didn't see it on any of these wiki pages:

The J5-15 connection coming off a '138 is a bit interesting.  That would 
imply some address decode expansion from a single chip select outta the 
processor.  Do you know what are the cpu side connections of the '138?

How does the daughtercard differentiate CS for uart 1 and uart 2?  (address 
line decode on the daughter card, with both using J5-15?)

Thanks.
