| | IBM PC - Wikipedia, the free encyclopedia |
 | | All IBM personal computers are software compatible with each other in general, but not every program will work in every machine. | | | The " IBM Personal Computer XT " was an enhanced machine designed for business use. | | | The predecessor of the current personal computers and progenitor of the IBM PC compatible hardware platform, it was introduced in August 1981. |

| | IBM PCjr - Wikipedia, the free encyclopedia |
| | The IBM PCjr was a relatively inexpensive home computer of the 1980s, and it was IBM 's first attempt to enter the educational and home computer markets. | | | In addition to promising a high degree of compatibility with the IBM PC, already a popular business computer, the PCjr offered built-in color graphics and sound comparable or superior to other popular home computers of the day. | | | In addition, many people compared it to the IBM PC rather than to the machines it was competing directly against. |

| | For example, 2.1 for the PCjr, 3.3 for the PS/2s. | | | IBM subjected the operating system to an extensive quality-assurance program, found well over 300 bugs, and decided to rewrite the programs. | | | An agreement was reached between the two, and "IBM PC-DOS 1.0" was ready for the introduction of the IBM PC in October 1981. |

| | History and Memories of the IBM PCjr and Tandy 1000 | | | The keyboard, what IBM thought would be considered a great innovation, was ultimately its largest drawback--while it claimed you could be 6 feet or more away from the computer in wireless mode, most people found they had to be no further than about two or three feet from the computer. | | | This IBM mirror of the PCC BBS files has a lot of programs specific to the PCjr, including documents that outline specific problems and workarounds, some music and graphics programs, patches to games to make them use the PCjr's 16-color graphics mode, and system utilities. |

| | IBM PCjr. |
| | Only a little: the PCjr is somewhat slower than previous IBM PCs, it can't support the 8087 arithmetic processor, and the current limitations on memory and disk may prevent the use of some large programs and data files. | | | From Ogo for the little ones, through introductory computer architecture for college classes, the PCjr is a credible vehicle for serious education with or about computers. | | | The real strength of the PCjr is that it is an IBM PC in every respect: same processor (the Intel 8088), same operating system (PC DOS), identical disk formats, and compatible displays. |

| | IBM named their computer the IBM Personal Computer Model 5150, although most people simply called it the IBM PC. | | | While IBM was not the first company to make a personal computer, IBM gained immediate respect because the company was the world's most successful manufacturer of mainframe computers. | | | The IBM Personal Computer XT Model 5160 was essentially an IBM PC with an internal storage device called a fixed disk (hard drive), and the IBM Personal Computer PC jr Model 4860 which was IBM's entry into the home computer market. |

| | PCjr History |
| | And best of all, the PCjr would run home software and the business software that was making the IBM PC popular. | | | The IBM machines were gaining in popularity and had good hardware support, but they were very expensive for a home user. | | | The PCjr's 4.77mhz Intel processor was speedy compared to the MOStek 6502 processor that powered the Apple ][ and the Commodore. |

| | The IBM PCjr is a personal computer, introduced in 1984 and sold through 1985. | | | As a result, the PCjr didn't sell well, and it is considered to be one of the bigger flops in the personal computing industry. | | | The lack of information about the PCjr probably isn't harming anybody; I just feel that the machine shouldn't be relegated to the "bit bucket." ("Bit bucket" is programmer's term for "lost.") These machines were interesting, and reading about them can give one a sense of perspective when contemplating today's 1.2 gigahertz behemoths. |

| | After launching the IBM PC (and its great success), IBM tried to stand out a standard for home computers, it created then the PC junior, which itself is a "light" version of the PC especially designed for home activities. | | | Two IBM PC junior models were available: a basic one and a enhanced one (supplied with 128k, 30 programs, a 5.25" floppy disk drive [360 KB] and its controller). | | | Despite its qualities, the PC jr had few success and never managed to replace the established home computers like Commodore 64, Apple II or Atari 800. |

Trivette, author of ``The Official Book of King's Quest'', a year before the IBM PCjr was announced IBM asked Sierra to create a game that would show off the new computers color graphics capabilities. | | | This is done through port 192 on the IBM PCjr by sending it 2 bytes in the following format: |
