"The first thing to think about when considering an IBM-compatible computer is, "How compatible is it?""
During development, Compaq engineers found that Microsoft Flight Simulator would not run because of what subLOGIC's Bruce Artwick described as "a bug in one of Intel's chips", forcing them to make their new computer bug compatible with the IBM PC. At first, few clones other than Compaq's offered truly full compatibility. Jerry Pournelle purchased an IBM PC in mid-1983, "rotten keyboard and all", because he had "four cubic feet of unevaluated software, much of which won't run on anything but an IBM PC. Although a lot of machines claim to be 100 percent IBM PC compatible, I've yet to have one arrive ... Alas, a lot of stuff doesn't run with Eagle, Z-100, Compupro, or anything else we have around here". Columbia University reported in January 1984 that Kermit ran without modification on Compaq and Columbia Data Products clones, but not on those from Eagle or Seequa. Other MS-DOS computers also required custom code.
Note : G25 has a sequential gear shift option that makes it more compatible so this chart is inaccurate for the G27 which does not have that feature. (Both the G25 and G27 have a sequential gear shift option however the G27 lacks the option to switch to a standard non-sequential manual transmission. Gears from reverse then gear 1, 2, 3, 4, 5 can be used in a standard H-Box pattern on the G25 so what is stated is wrong it is in fact the H-Box that is unavailable on the G27 not the sequential shift, it lacks the H-Box option unlike the G25)
The following boards are fully or almost fully compatible with both the Arduino hardware and software, including being able to accept "shield" daughterboards.
Microsoft's competing OS was intended initially to operate on a similar varied spectrum of hardware, although all based on the 8086 processor. Thus, MS-DOS was for several years sold only as an OEM product. There was no Microsoft-branded MS-DOS: MS-DOS could not be purchased directly from Microsoft, and each OEM release was packaged with the trade dress of the given PC vendor. Malfunctions were to be reported to the OEM, not to Microsoft. However, as machines that were compatible with IBM hardware—thus supporting direct calls to the hardware—became widespread, it soon became clear that the OEM versions of MS-DOS were virtually identical, except perhaps for the provision of a few utility programs.
The term "IBM PC compatible" is not commonly used presently because all current mainstream desktop and laptop computers are based on the PC architecture, and IBM no longer makes PCs. The competing hardware architectures have either been discontinued or, like the Amiga, have been relegated to niche, enthusiast markets. In the past, the most successful exception was Apple's Macintosh platform, which used non-Intel processors from its inception. Although Macintosh was initially based on the Motorola 68000 family, then transitioned to the PowerPC architecture, Macintosh computers transitioned to Intel processors beginning in 2006. Today's Macintosh computers share the same system architecture as their Wintel counterparts and can boot Microsoft Windows without a DOS Compatibility Card.
"Compatible", "generic", or "alternative brand" are cartridges manufactured by third party companies and sold under different brand names. Compatible cartridges may vary slightly in look, design and page yield to their OEM counterparts, sometimes due to patents or design copyrights. Generic cartridges are cheaper, often significantly so, than original manufacturer cartridges. They may be less reliable, depending upon the manufacturer. Some contain more toner than OEM cartridges, printing more pages. Some compatible toner cartridges may be of similar quality to their OEM competitors, but many are not.
Problems with compatible toners may be caused by various factors including different melting points, different electrostatic qualities, different pigments and different particle sizes, any of which can lead to poor print quality, dirty background or in extreme cases, damage to equipment.
Compatible ink (or compatible toner) is manufactured by third party manufacturers and is designed to work in designated printers without infringing on patents of printer manufacturers. Compatible inks and toners may come in a variety of packaging including sealed plastic wraps or taped plastic wraps. Regardless of packaging, compatible products are generally priced lower than original equipment manufacturer (OEM) brand inks and toners.
All types of compatible ink cartridges are different and vary from supplier to supplier. This is due to the type of ink in the printer, the chips (or no chip) on the cartridge and the actual manufacture of the cartridge itself.
In general, plug-compatible systems are designed where industry or de facto standards have rigorously defined the environment, and there is a large installed population of machines that can benefit from third-party enhancements. Plug compatible does not mean identical replacement. However, nothing prevents a company from developing follow-on products that are backward-compatible with its own early products.
Make Compatible is a program developed by Microsoft that is included with Windows 9x operating systems. It changes per-program system settings in Windows to allow Windows 3.1 programs that are tailored specifically to that platform to execute under newer versions. The name of the program image file for Make Compatible is mkcompat.exe, and it is stored in the \Windows\System directory.
The first example of plug compatible IBM subsystems were tape drives and controls offered by Telex beginning 1965. Memorex in 1968 was first to enter the IBM plug-compatible disk followed shortly thereafter by a number of suppliers such as CDC, Itel, and Storage Technology Corporation. This was boosted by the world's largest user of computing equipment in both directions.
While there has been considerable debate and litigation involving the ink and toner patents of printer manufacturers, third party manufacturers continue to thrive. Manufacturers of compatible ink and toner products currently control about 25% the ink and toner market well over $8 Billion annually.
Compatible ink is manufactured for several types of machines including fax machines, laser printers, inkjet printers, multifunction printers, and copiers. Aside from compatible products, three other sources of consumables are also available to supply these machines, including OEM brand ink and toner, remanufactured toner and ink cartridges, and refilled ink and toner cartridges. Compatible ink manufacturers differentiate their product by using all new parts, whereas other ink replacements recycle used OEM parts. Compatible ink and toner products tend to offer greater value than original, genuine OEM ink and toner cartridges. Reducing cost for the end user, ink and toner manufactured by third party manufacturers is classified as compatible when consisting of new parts for a third party printer.
Each line names an application program, and gives a hexadecimal numeric constant to associate with that program. The hexadecimal numeric constant encodes the compatibility bitflags for that particular application, that Windows applies when the application is executed. Make Compatible merely provides a graphical user interface for editing these flags in an easy way, rather than editing win.ini manually, with a text editor. It allows one to set and unset individual flags without having to know their numeric values.
Plug compatible refers to "hardware that is designed to perform exactly like another vendor's product."
Compatible Partners is an online relationship service. Compatible Partners serves the gay and lesbian community, matching men and women with compatible singles of the same sex, taking into consideration what it considers the key dimensions of personality. Compatible Partners was launched by eHarmony Inc. on March 31, 2009. The website was launched in response to a settlement with the state of New Jersey, following a lawsuit against eHarmony for discrimination against same-sex couples.
One recurring theme in plug-compatible systems is the ability to be bug compatible as well. That is, if the forerunner system had software or interface problems, then the successor must have (or simulate) the same problems. Otherwise, the new system may generate unpredictable results, defeating the full compatibility objective. Thus, it is important for customers to understand the difference between a "bug" and a "feature", where the latter is defined as an intentional modification to the previous system (e.g. higher speed, lighter weight, smaller package, better operator controls, etc.).
Ink Compatible was released worldwide via Ron Jarzombek's EclecticElectric label, except for Japan and Southeast Asia where it was released by Avalon/Marquee. It was released in Russia on Iron d.
