The Commodore SX-64, also known as the Executive 64, or VIP-64 in Europe, was a portable, briefcase/suitcase-size “luggable” version of the popular Commodore 64 home computer and holds the distinction of being the first full-color portable computer.
The SX-64 featured a built-in five-inch composite monitor and a built-in 1541 floppy drive. It weighed 23 lb (10.5 kg). The machine was carried by its sturdy handle, which doubled as an adjustable stand. It was announced in January 1983 and released a year later, at $995.
