Introduction

The IBM PCjr is a personal computer introduced in 1983 and sold through 1985. It had some nice features that other computers did not have at the time, but it was not compatible enough with the rest of the IBM PC family to be successful as a pure PC clone, and initially it was too expensive to compete against "home" machines such as the Apple ][ and the Commodore 64. As a result, the IBM PCjr did not sell well and it is considered to be one of the bigger flops in the industry.

I still like mine though. These web pages are an attempt to preserve the history and technical information of the IBM PCjr.

If you have questions or comments, please email me at mbbrutman at gmail.com. Please, no spam or unreasonable requests. I am interested in hearing your stories about the PCjr and meeting other owners of these fascinating machines.
