The difference with the original model 1000, is that the CPU (Intel 8088) can be set to two different speeds: 4.77 MHz and 7.16 MHz thus offering more speed than the original [IBM PC](/museum/ibm-pc-model-5150/) on the same software. The SX also comes with more memory (384 KB) than the [Tandy 1000](/museum/tandy-radio-shack-1000/) (128 KB). --- Contributors: Derek McDonald (aka “Skel”)
