**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.

**82497/492   Cache Controller / Cache RAM (for P54 Pentium)    <Nov94
***Notes:...
***Info:
The 82497 Cache Controller and multiple 82492 Cache SRAMs combine with
the Pentium processor  (735\90, 810\100) to form a  CPU Cache chip set
designed for high performance servers and function-rich desktops.  The
high-speed interconnect between the  CPU and cache components has been
optimized to  provide zero-wait state  operation. This CPU  Cache chip
set  is fully  compatible with  existing  software, and  has new  data
integrity features for mission critical applications.

The 82497 cache controller implements the MESI write-back protocol for
full multiprocessing support. Dual  ported buffers and registers allow
the 82497  to concurrently  handle CPU bus,  memory bus,  and internal
cache operation for maximum performance.

The  82492 is a  customized high-performance  SRAM that  supports 32-,
64-, 128-bit wide memory bus widths, 16-, 32-, and 64-byte line sizes,
and optional sectoring.  The data path between the  CPU bus and memory
bus  is separated  by the  82492, allowing  the CPU  bus  to handshake
synchronously,  asynchronously,  or   with  a  strobed  protocol,  and
allowing concurrent CPU bus and memory bus operations.
