   No historical SNR with a pulsar is known except for Crab nebula, and
   all theoretical discussion about pulsar has made with only Crab pulsar.
   The hard X-ray point source RXJ 1443-6228 in RCW86, one of the
   historical SNR, has a spectrum like that of a pulsar. However, the
   pulsation of it has not been detected yet. On the other hand, RCW86 is
   one of the SNRs which accelerate high energy cosmic rays, although it
   has many differences from SN1006. The discovery of the pulsation of RXJ
   1443-6228 will reveal not only the information of the second historical
   pulsar and SNR itself, but also that the SNRs which differ from typical
   SN1006-like SNR can also create high energy particles.
