**82C836   Single Chip 386sx (SCATsx)                              <91
***Info:
The 82C836, also  known as SCATsx, is a VLSI  device that incorporates
most of  the motherboard logic  required to  build a low  cost, highly
integrated,  IBM PC  AT compatible  computer using  the 386sx.   It is
designed to be  used in conjunction with other  Chips and Technologies
controllers such as  the 82C45X VGA Controller,  and 82C710 integrated
Floppy  Disk  and  Multifunction  Controller.  When  used  with  these
devices, the  82C836 acts as the  heart of a highly  integrated system
that significantly reduces the  motherboard size, component count, and
the need for many I/O channel  slots. Figure 1 [see datasheet] shows a
block diagram for the basic system architecture.
