What was the 386SX?
The 386SX Microprocessor is a 32-bit CPU with a 16-bit external data bus and a 24-bit external address bus. The 386SX CPU brings the high performance software of the Intel 386 Architecture to midrange systems.
What is the difference between SX and DX in a 386 chip?
The SX was a 32-bit chip internally, but only had a 16-bit path to the system memory. The DX was a full 32-bit chip. It could address memory faster, and more of it. You could only put 16 MB of memory on a 386 SX.
When did the 386SX come out?
1988
In 1988, Intel introduced the 80386SX, most often referred to as the 386SX, a cut-down version of the 80386 with a 16-bit data bus, mainly intended for lower-cost PCs aimed at the home, educational, and small-business markets, while the 386DX remained the high-end variant used in workstations, servers, and other …
What is a 486 computer?
The 486 was a 32-bit CPU with thirty-two 32-bit registers and 1.1M to 1.2M transistors in a 168- or 169-pin PGA package. Real Mode performed as an 8086 CPU that addressed 1MB of RAM, while Protected Mode addressed 4GB of physical RAM and 64TB of virtual memory.
How fast is 386?
The Deskpro 386 running at up to 16 megahertz (a measure of processing speed) is more than four times faster than a PC XT running at 4.77 megahertz because the 80386 chip digests data and software instructions in bigger chunks than either the 8088 chip of the PC XT or the 80286 chip of the PC AT running at 6 or 8 …
What was the first 64 bit processor?
64-bit address timeline. MIPS Computer Systems produces the first 64-bit microprocessor, the R4000, which implements the MIPS III architecture, the third revision of its MIPS architecture.
What is difference between 80386DX and 80386SX?
The 80386SX Intel processor has a 16-bit external bus and a 24-bit address bus. The 80386DX Intel processor has a 32-bit external bus and a 32-bit address bus. Memory access is faster with the DX Intel processor.
What did computers look like in 1987?
Major computer events in 1987 IBM introduced the PS/2 personal computer with improved graphics, a 3.5-inch diskette drive, proprietary bus to help prevent clones, and a bidirectional 8-bit port. CompuServe introduced the GIF standard and images in 1987.
What did a computer look like in 1986?
New computer products and services introduced in 1986 The computer contained one megabyte of RAM, a new keyboard that contained cursors and numeric keypad, and sold for $2,600. The AT or 101 key keyboard was introduced by IBM.
What came after 486?
The follow-up for the 486 was the Pentium, at least in Intel’s case. But several companies made 486 CPUs, and several of those released their own follow-ups to the 486, including AMD and Cyrix.
Is 80386DX a coprocessor?
The 80386DX or 386DX processor was the original 386 processor renamed and not a different 386 processor. Not to be confused with the 80387. The 80387DX is a mathematical coprocessor created by Intel for their i386 line of CPUs.
What is the difference between 80386 and 80486?
The 80486 architecture has been ungraded such that half of its instructions are executed in 1 clock cycle instead of two clock cycles. It has 80386 like microprocessor and 80387 like numeric coprocessor.
How much RAM did early computers have?
From the factory the PC was equipped with either 16 KB or 64 KB of RAM.
What was the Internet like in 1987?
1987: The Internet grows By 1987, there were nearly 30,000 hosts on the Internet. The original Arpanet protocol had been limited to 1,000 hosts, but the adoption of the TCP/IP standard made larger numbers of hosts possible.
Does 1986 have Internet?
NSFNET went online in 1986 and connected the supercomputer centers at 56,000 bits per second—the speed of a typical computer modem today. In a short time, the network became congested and, by 1988, its links were upgraded to 1.5 megabits per second.

Can you burn circuit boards for gold?
Piles of printed circuit boards and other electronic scrap are burned, leaving behind ash and the gold they contain. Quantities of dust and dirt found in old jewelry factories can be burned, leaving both ash and quantities of gold, silver and other precious metals.
