**82497/492 Cache Controller / Cache RAM (for P54 Pentium) <Nov94
***Notes:

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 $.
