The Compaq SLT/286 — The Slim Business Laptop
Released in 1988, the Compaq SLT/286 (Slim-Line Technology) was Compaq’s attempt to produce a slimmer, lighter laptop than the original LTE while maintaining full IBM AT compatibility. Using an Intel 80286 processor at 12 MHz with 640 KB of RAM and an internal 3.5-inch floppy drive, it offered a thinner profile than the LTE in a package targeting business users who needed genuine portability without sacrificing performance. The SLT/286 supported an optional internal hard drive and an external VGA display for desktop use.
Slim-Line Design
The ”SLT” designation — Slim-Line Technology — reflected Compaq’s engineering effort to reduce the thickness of their laptop design. While not dramatically thinner than competing machines, the SLT/286’s reduced profile made it more comfortable to carry and use in confined spaces such as aircraft seats and train compartments. This focus on physical dimensions alongside technical specifications marked an important shift in laptop design priorities — recognising that size and weight mattered as much as performance to mobile users.
VGA Support
The SLT/286’s support for external VGA display was a practical feature for users who needed the laptop’s portability on the road but wanted a full-size display when at their desk. This dual-mode capability — laptop display for travel, VGA monitor for office use — anticipated the docking station concept that would become standard in business laptop design throughout the 1990s.
