**82C802G/GP     System/Power Management Controller (cached)      c:93
***Notes:
Green version of the 82C802.  Supports cached 486 systems running from
20 MHz to  50 MHz. Also supports write-back cache and  VESA LB. PCI is
also supported via the 82C822 bridge chip.

This  is an  amalgamation of  two different  datasheets, the  802G and
802GP. There is very little difference, see the features section.
