PredecessorMultiSpeed

The ProSpeed was a line of laptop computers developed by NEC in 1988. It served as the replacement for their earlier MultiSpeed line and was introduced simultaneously with their slimmer and less heavy UltraLite line of notebook computers. The i386SX-equipped CSX model, released in September 1989, was the first laptop with a color LCD. It was also one of the first laptops to be offered with a docking station. The CSX model was featured on the front cover of PC Magazine.
