  We discuss the results from deep Chandra LETG observations of the supernova
remnant 1987A (SNR 1987A). We find that a distribution of shocks, spanning the
same range of velocities (from 300 to 1700 km/s) as deduced in the first part
of our analysis (Zhekov et al. 2005, ApJL, 628, L127), can account for the
entire X-ray spectrum of this object. The post-shock temperature distribution
is bimodal, peaking at kT 0.5 and 3 keV. Abundances inferred from the X-ray
spectrum have values similar to those for the inner circumstellar ring, except
that the abundances of nitrogen and oxygen are approximately a factor of two
lower than those inferred from the optical/UV spectrum. The velocity of the
X-ray emitting plasma has decreased since 1999, apparently because the blast
wave has entered the main body of the inner circumstellar ring.
