**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 $.
