  64           developed as an open alternative to the IBM MicroChannel bus.

  66           The EISA bus provided some of the features of the IBM MicroChannel
  67           bus while maintaining backward compatibility with cards made for
  68           the older ISA bus.  The EISA bus saw limited use between 1988 and
  69           1995 when it was made obsolete by the PCI bus.
