  Intel 80386 processor family
The third x86 generation of x86 microprocessors, Intel 80386 (i386) was a 32-bit microprocessor backwards compatible with previous generations of 80x86 CPUs.
The Intel 80386 was produced at speeds up to 33 MHz, AMD produced even faster 40 MHz version.
The 80386SX processors were manufactured in 100-pin package, or 32 pins less than the number of pins on DX package.

  X86 architecture - Wikipedia, the free encyclopedia
The x86 architecture first appeared inside the Intel 8086 CPU in 1978; the 8086 was a development of the Intel 8080 processor (which itself followed the 4004 and 8008), and programs in 8080 assembler language could be mechanically translated to equivalent programs in 8086 assembler language.
An exception to this design is the Intel 80386SX, which is 32-bit with 24-bit addressing and a 16-bit data bus.
The Intel 80387 math co-processor was integrated into the next CPU in the series, the Intel 80486 (the 486SX, sold as a budget processor, had its co-processor disabled or removed).

The 80186 was an improvement on the Intel 8086 and Intel 8088.
The Intel 8086 was based on the design of the Intel 8080 and Intel 8085 (it was source compatible with the 8080) with a similar register set, but was expanded to 16 bits.
Intel bubble memory was on the market for a while, but faded away as better and cheaper memory technologies arrived.

 Lloyd Borrett - Computing - Articles - The Intel 80386 SX
Much has been said recently about the introduction of the Intel 80386SX or P9, but as usual little has been said about the real benefits of the 80386SX, and where it fits into the new generation of personal computers and PC based solutions that are coming our way.
The Intel 80386SX is to the 80386 as the original 8088 is to the 8086.
However, the performance difference between the 80386 and the 80386SX is not as great as that between the 8086 and the 8088.

 Intel 80387SX - Wikipedia, the free encyclopedia
The Intel 80387SX was the math coprocessor for the Intel 80386SX series of microprocessors.
The coprocessor was designed only to work with the SX variant of the 386, rather than the standard (later re-named DX) Intel 80386.
This was because of the 386SX's 16 bit data bus which was modified from the original 386 32 bit data bus.

 Lloyd Borrett - Computing - Articles - Which CPU Should You Purchase
IBM and Microsoft made an announcement at Comdex in November that their "Platform for the 90s" was to be based on the capabilities of the Intel 80386SX, 80386, 80486 and future Intel family microprocessors.
Intel themselves have been running an advertising campaign in the USA which stresses you should always choose an 80386SX over an 80286 or earlier microprocessor.
Firstly, Intel having licensed other chip makers to manufacture the 80286 chip found these other manufacturers had not only been gradually increasing the clock speed of the 80286 but they had also been lowering prices.

The major difference between the 80386DX processor and the 80386SX processor is that the DX flavor is a 32-bit processor, while the SX flavor is a 16-bit processor.
This time, Intel was trying to attract customers who could not justify the price of the more functional chip, so Intel simply downgraded the 80486DX, marketing it as a different chip and selling it at a lower price.
Intel decided to develop a new standard for upgrading a processor on system boards, beginning with the 80486 chips and continuing with the Pentium class processors.

 Computer Knowledge - Intel 80x Processors
While introduced at the same time as the Intel 8088 and was a better processor, the 8086 was not picked for the first IBM personal computers because of the difficulty of building 16-bit accessories versus 8-bit accessories which the 8088 supported.
The 80386SX chip was designed to fill a market gap between the 80286 and 80386 which took off slowly.
The 80486 was also the first microprocessor Intel produced which had a numeric coprocessor built into the main chip.

With the exception of integrated components, the Intel 80186 microprocessor is not very different from the 8086, and, because of this, the 80186 may be considered as an embedded version of 8086.
Although the Intel 80186 was not widely used in the computers as the 8086 and 80286 did, it was successful in embedded processor market.
The Intel 80188 is a version of the Intel 80186 microprocessor with an 8 bit external data bus, instead of 16 bit.
