===PC-98===

(Not to be confused with incompatible NEC's incompatible [[PC-98]] series)

Aimed at systems to be used with [[Windows 98]] or [[Windows 2000]]. Required:

* 200 MHz Pentium processor with [[MMX (instruction set)|MMX]] technology (or equivalent performance)

* 256 KB [[L2 cache]]

* 32 MB [[Random -access memory|RAM]] (recommended: 64 MB of 66 MHz DRAM)

* [[Advanced Configuration and Power Interface|ACPI]] 1.0 (including power button behavior)

* Fast [[BIOS]] power-up (limited RAM test, no floppy test, minimal startup display, etc.)

* BIOS [[Year 2000 problem|Y2K]] compliance

Line 52:

* 300 MHz CPU

* 64 MB RAM

* [[Universal Serial Bus|USB]]

* Comprehensive color-coding scheme for ports and connectors (see below)

Strongly discouraged:

Perhaps the most end-user visible and lasting impact of PC 99 was that it introduced a [[color code]] for the various standard types of plugs and connectors used on PCs.<ref>[http://www.microsoft.com/whdc/archive/pcguides.mspx PC 99 System Design Guide], Intel Corporation and Microsoft Corporation, 14 July 1999. Chapter 3: PC 99 basic requirements ([http://download.microsoft.com/download/win2000pro/PCG/1.0/NT5/EN-US/pc99v1a.exe PC 99 System Design Guide (Self-extracting .exe archive)] {{Webarchive|url=https://web.archive.org/web/20070216004214/http://download.microsoft.com/download/win2000pro/PCG/1.0/NT5/EN-US/pc99v1a.exe |date=2007-02-16 }}. Requirement 3.18.3: Systems use a color-coding scheme for connectors and ports. Accessed 2009-02-05</ref> As many of the connectors look very similar, particularly to a novice PC user, this made it far easier for people to connect peripherals to the correct ports on a PC. This color code was gradually adopted by almost all PC and [[PC motherboard|motherboard]] manufacturers. Some of the color codes have also been widely adopted by peripheral manufacturers.
