IBM Portable PC 5155

IBM PC · 1984

IBM's answer to the Compaq Portable, two years late: XT internals in a luggable case with a nine-inch amber screen and a fold-up keyboard. Thirty pounds of it. It sold poorly against Compaq's own machine, which makes it markedly less common than the desktop XT, and it is a striking object.
