Compaq SLT was a line of portable computers from Compaq. The SLT series was the successor to the Portable III and the predecessor of the more famous Compaq LTE. Two models have been produced in the SLT series. The first model, called SLT / 286, is considered one of the most striking units in laptop history for its battery life and superior performance compared to competing models. It is also notable for being Compaq's first laptop computer. The SLT / 286 had a 12 MHz Harris or Intel 80C286 processor (both brands were used during the production of the SLT / 286) and a grayscale VGA LCD display, the very first laptop to feature this feature.
