**ACC82C100  Single-Chip PC/XT Systems-Controller                  c90
***Info:
The  82C101  is a  high  performance  CMOS  PC/XT bus  and  peripheral
controller  for designers  to build  a PC  BUS-compatible single-board
computer  with "turbo"  power, The  82C101 replaces  all  TTL/SSI/ MSI
devices  including six  Intel  peripheral controller  ICs required  to
build a typical "Turbo XT."   The 82C101 integrates all the controller
functions of a typical  "Turbo/XT" high performance motherboard.  This
high  integration  not  only  increases system  performance  but  also
reduces  the total system  cost because  of lower  power requirements,
increased reliability, and reduced components and board size.
