It retained the IBM PC's [[Intel 8088|8088]] [[CPU]] and [[BIOS]] interface, but provided enhanced graphics and sound, [[ROM cartridge]] slots, built-in joystick ports, and an infrared wireless keyboard. The PCjr supported expansion via "sidecar" modules, which could be attached to the side of the unit. Despite widespread anticipation, the PCjr was ultimately unsuccessful in the market. It was only partially [[IBM PC compatible]], limiting support for IBM's software library, its [[chiclet keyboard]] was widely criticized for its poor quality and limited expandability, and it was initially offered with a maximum of {{val|128|ul=KB}} of RAM, insufficient for many PC programs.
