**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

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.

**Notes:
You eventually get  to know when a  board is made by PC  Chips just by
looking at it.
 
Here is a test:
1.  No manufacture name, or one of the above.
2.  If the board has a lots of components that sound like a well known 
    part but aren't the well known part. i.e. 'HX Pro' instead of 
    '430HX'
3a. A really good feature set where you think, that's exactly what I'm 
    looking for.
 b. The features don't really work as intended. 
4.  The price is fantastic.
5.  Its disappointing on closer examination.

PC Chips is  renowned for making crap products. Some  are actually not
too bad, they're no worse than  your average brand. However some are a
nightmare either by design or  just poorly made. Fake components glued
on is not  uncommon. Fake labels over other components.  PCB's so thin
they require low insertion force ISA connectors, every trick to save a
few $.
