**Spelling errors/mistyped words
Yes, I  know there are  spelling errors,  and things are  mistyped. It
seems no matter  how hard I try  my fingers hit 't'  twice when typing
'compatible' rendering it 'compattible' numerous, (thousands actually)
times.  I  don't have the  time or the will  to check the  spelling of
everything. Basic spell checking has been peformed. Please let me know
if  there is  anything that  would lead  to incorrect  information, or
something  is so  mangled  that  it needs  revising.  But  if you  can
basically  understand  what was  intended,  just  cope with  it.  Just
cope:-)

BTW, "110" port is  an "I/O" port that has been OCRed  badly, as is an
"1/0" port.

**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.

**82497/492   Cache Controller / Cache RAM (for P54 Pentium)    <Nov94
***Notes:
Date source: 1995_Intel_Pentium_Processors_and_Related_Components.pdf

The info and features section have  been solely sourced from the first
source.   The  second source  provides  far  more detail.   Additional
information in the configurations section  and below have been sourced
from the second.

"Although the 82497 Cache Controller  is part of the Pentium processor
(735\90, 815\100, 1000\120, 1110\133) CPU-Cache Chip Set and the 82496
Cache  Controller is part  of the  Pentium Processor  (510\60, 567\66)
Chip  Set, the  two parts  are functionally  identical except  for the
differences noted in this section." - p491

Aside  from some  minor  differences in  pin  configuration, the  main
difference is the direct support  for 3.3V processors. This chipset is
still a 5V part. The cache operates at bus speed, max 66MHz.


This  chip was  used on  the Pentium  90MHz CPU  complexes of  Intel's
Xpress  platform.   Specifically  the BXCPUPENT90  (Single  90MHz,  16
82492s). Also found on IBM 9595/Server 500 Pentium 90MHz complexes.
