The IBM Portable Personal Computer 5155 model 68 is an early portable computer developed by IBM after the success of the suitcase-size Compaq Portable. It was released in February 1984 and was quickly replaced by the IBM Convertible, only roughly two years after its debut.
The IBM 5155, also known as the IBM Portable Personal Computer, was introduced in February 1984. It was IBM's first attempt at creating a portable computer. The IBM 5155 featured a built-in 9-inch monochrome display, two 5.25-inch floppy disk drives, and an Intel 8088 processor running at 4.77 MHz. It weighed around 30 pounds (13.6 kg) and had a handle for easier transportation. Despite its bulky size, it was considered highly portable for its time.
The unit also has a new, lightweight keyboard and a universal power supply. The system board is the same as that of the IBM Personal Computer XT with 256KB of memory that is expandable to 512Kb using the memory expansion option.
Five expansion slots are available for the connection of most IBM Personal Computer options. The system has identical function and performance characteristics to an equivalently configured IBM Personal Computer.
