The IBM PCjr (read "PC junior") was IBM's first attempt to enter the market for relatively inexpensive educational and home-use personal computers. The PCjr, IBM model number 4860, retained the IBM PC's 8088 CPU and BIOS interface for compatibility, but differences in the PCjr's architecture, as well as other design and implementation decisions, eventually led the PCjr to be a commercial failure in the marketplace.
