**82C110   IBM PS/2 Model 30/Super XT                                ?
***Notes:...
***Info:
The 82C110 is a single chip implementation of most of the system logic
necessary to implement a super XT compatible system with PS/2 Model 30
functionality using either an  8086 or 8088 microprocessor. The 82C110
can  be used  with either  8  or 16-bit  microprocessors.  The  82C110
includes features  which will enable  the PC manufacturer to  design a
super PS/2 Model 30/XT  compatible system with the highest performance
at  10  MHz  zero  wait   state  system  with  an  8086,  the  highest
functionality  with  dual  clock  and  2.5 MB  DRAM  {with  integrated
Extended Memory  System control  logic}, the highest  integration with
the lowest component count SMT design.

The 82C110 can be combined with-CHIPs’ 82C601 Multifunction Controller
and 82C451 VGA Graphics Controller to provide a high performance, high
integration PS/2 Model 30 type system.

The 82C110 supports most of the peripheral functions on the PS/2 Model
30 planar board; 8284 compatible  clock generator with the option of 2
independent  oscillators, 8288 compatible  bus controller,  8237 comp-
atible  DMA  controller, 8259  compatible  interrupt controller,  8254
compatible  timer/counter,  8255 compatible  peripheral  I/O port.  XT
Keyboard interface, Parity Generation and Checking for DRAM memory and
memory controller for DRAM memory sub-system.

The  82C110 enables  the  user to  add  PS/2 Model  30 superset  func-
tionality on the planar board: dual clock, with synchronized switching
between  the two,  clocks.  built-in  Lotus-Intel-Microsoft  (LIM) EMS
support for up to 2.5 Megabytes of DRAM.

The  82C110 supports a  very flexible  memory architecture.   The DRAM
controller  supports 64K,  256K  and  1M DRAMs.   These  DRAMs gen  be
organized in  four banks of up  to a maximum  of 2.5 MB on  the planar
board. The  2.5 MB memory can  be implemented with  2 banks of 7M  X 1
DRAMs, partitioned locally as 540KB of real memory and 1,875 MB of EMS
memory. The 82C110 is packaged in a 100-pin plastic flatpack.

***Notes:...
***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.
