**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 $.

***Info:
INTRODUCTION
This document describes the two separate functions, Address Buffer and
Data Buffer,  available in  the WD7625LV chip.  A strapping  input pin
selects  the Data  Buffer  Function when  strapped  low, otherwise  it
selects the Address Buffer Function.

GENERAL DESCRIPTION
The  WD7625LV is  a  combination design  which  includes two  separate
functions: Address  Buffer and Data  Buffer in one chip.   A strapping
input pin  selects the  Data Buffer  Function if  it is  strapped low;
otherwise, it  selects the Address  Buffer Function. For  designs that
use  both  the data  buffer  and  the  address buffer  functions,  two
WD7625LV devices are needed in the system.

In the Address Buffer Function,  the WD7625LV is an address buffer and
power management chip.  

In the Data Buffer Function, the WD7625LV is a data buffer, IDE buffer
and I/O register device for the WD7x00 16-bit chip sets.
