**Why this document is not GPL or a wiki
The document is copyright, it is NOT GPL'ed text. While the GPL is a
fantastic idea, I have chosen not to make this freely copied and
modified. The reasons are as follows:
1. GPL text tends to be copied...EVERYWHERE. For example, if you look
up a subject on wikipedia, then try to get more information, or a
different perspective on say about.com. There you find the EXACT
SAME TEXT. This is what mirrors are for. It's an unintended
consequence, but it can lead to misinformation being spread
everywhere. A bigger problem.
2. There seems to be fewer and fewer informative websites. It used to
be that if you searched for something you would find a website
about a particular subject. Now you tend to find the encyclopedia
and often nothing else (well quickly).
In addition the majority of this text is quotes.
The wiki concept is a good idea, but they have problems. Because no
one "owns" the work they seem to go to two extremes. Either no one
maintains them, or there are edit wars. Also anyone can edit them.

**CS8281 NEATsx (386SX) (82C811/812/215/206) c:Dec89
***Info:
The CS8281 NEATsx CHlPSet, which is composed of four VLSI devices, is
a high-performance, 100%-compatible enhanced implementation of the
control logic used in the IBM PC AT. The flexible architecture of the
NEATsx CHIPSet allows it to be used as the basis for any
386sx-compatible system.
The CS8281 NEATsx CHIPSet provides a complete 386sx PC/AT compatible
system, requiring only 24 logic components plus memory devices.
The CS8281 NEATsx CHIPSet consists of the 82C811 CPU/bus controller,
the 82C812 page/interleave and EMS memory controller, the 82C215
data/address buffer, and the 82C206 integrated peripherals controller
(IPC).
The NEATsx CHIPSet supports a local CPU bus, a 16-bit system memory
bus, and the AT buses as shown in the NEATsx system block diagram [see
datasheet]. The 82C811 provides synchronization and control signals
for all buses. The 82C811 also provides an independent AT bus clock
and allows for dynamic selection between the processor clock and a
user~selectable AT bus clock. Because command delays and wait states
are configured by software, peripheral boards are provided with
maximum flexibility.
The 82C812 page/interleave and EMS memory controller provides an
interleaved memory subsystem design with page mode operation. It sup-
ports up to 8MB of DRAM with combinations of 256Kb and 1Mb DRAMs. The
processor can operate at 16 MHz with 0.7 wait state memory accesses,
using 100 nsec DRAMs. This is possible through a page interleaved
memory scheme. A RAM shadowing feature allows faster execution of
EPROM stored BIOS code by downloading and executing code from RAM. in
a DOS environment memory above 1MB can be used as EMS memory.
The 82C215 data/address buffer provides buffering and latching between
the local CPU address bus and the peripheral address bus. It also
provides buffering between the local CPU data bus and the memory data
bus. Parity bit generation and error detection logic resides in the
82C215.
The 82C206 integrated peripherals controller is an integral part of
the NEATsx CHIPSet. It is described in the 82C206 data book.
System Overview
The CS8281 NEATsx CHIPSet is designed for use in 12-16 MHz 80386 based
systems and provides complete support for the IBM PC AT bus. Four
buses are supported by the CS8281 NEATsx CHIPSet: the CPU local bus (A
and D); the system memory bus (MA and MD); the I/O channel bus (SA and
SD); and the X bus (XA and XD). The system memory bus provides an
interface between the CPU and the DRAMs and EPROMS controlled by the
82C812. The I/O channel bus refers to the bus supporting the
AT-compatible bus adapters which can be either 8- or 16-bit devices.
The X bus is the peripheral bus to which the 82C206 IPC and other
peripherals are attached in an IBM PC AT.
