The Portable PC was IBM's first carry-around PC. It still needed to be plugged in to work and weighed 30lbs, so it was quite a chore to carry around. Introduced in 1984, it offered an XT in a small box. It used the same motherboard as the XT but included a 9" Amber screen built into the case. The keyboard attached to the front of the case making it very simple to carry around, if you could handle the weight of it.
