I'm not sure of what you mean by A and B sides in sequence *AND* 180 
degrees apart.  The way it works on a 200 select if all selection at 
selected would be and assuming the carousel is set to play A1 first:
- A1 will play (A side of the A1/A2 record slot)
- Followed by L4 (B side of the L3/L4 record slot)
- Followed by A3 (A side of the A3/A4 record slot)
- and the pattern continues.

I may have this off by one slot, but after playing a selection the 
opposite side is played 180 degrees apart plus one selection.  A side 
and B side playing position are not actually 180 degrees apart.  They 
are 180 degrees apart + or - one half record slot apart depending upon 
you perspective.  Going from the A play position to the B play position 
in the clockwise direction the separation is 178.2 degrees apart.

The bottom line is that the if multiple selection are made it is 
unlikely that the A and B sides of the same record will play in 
sequence.  The only way to guarantee that this will happen is to select 
the A side first, wait till the record begins to load, select the B 
side, and then do not select anything else until the B side is playing.
