**82C235   Single Chip AT (SCAT)                                   c89
***Notes:
This info  is from  the original datasheet,  there is also  a revision
2.0.

***Info:
The 82C235 is a VLSI  device that incorporates most of the motherboard
logic  required  to  build   a  low-cost,  highly-integrated,  IBM  PC
AT-compatible computer. It is designed  to be used in conjunction with
other  Chips  and Technologies  controllers  such  as  the 82C45X  VGA
Controller,  the 820601  Multifunction Controller,  the  82C765 Floppy
Disk   Controller,  and   the  82C710   Integrated  Floppy   Disk  and
Multifunction  Controller. When  used with  these devices,  the 82C235
acts as  the heart  of a highly  integrated system  that significantly
reduces motherboard size,  component count, and the need  for many I/O
channel slots.
