 THE IBM PCjr - A Home Version of the PC in 1983
The PCjr was introduced on November 1, 1983 and sold for $998 with 64K of RAM or $1918 with 128K and a 5.25" floppy disk drive.
The PCjr was IBM's attempt to market a home and student version of their more powerful PC business machine.
The machine never achieved a good market niche, as it was more expensive than the typical home computer of the time and didn't have the memory, hard drive, or card expansion capabilities of the standard IBM-PC.

 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.
Whether any given piece of software is compatible with the PCjr is hard to predict with certainty, but there are a few simple considerations to take into account.

 IBM PCjr
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.

 IBM PCjr: Information From Answers.com
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.
Unable to compete with the C64 and Apple IIe and IIc, let alone the forthcoming Atari ST and Commodore Amiga, IBM withdrew the PCjr from the marketplace in mid-1985.
