Included with the 386SX−9100 notebook, the LEP−9100 AC power supply served as both an external power source and a battery charging solution for Leading Edge's portable system. Designed for broad electrical compatibility, the adapter supported worldwide input voltages and used a standard IEC power connector, making replacements easy if the original cable was misplaced. Its dual−mode output allowed the laptop to operate from wall power while managing battery charging in the background. Styled to visually match the notebook itself, the compact beige unit integrated status indicators and generous cable lengths to provide flexibility for desk or travel use.

Among the peripherals commonly shipped with later Leading Edge systems was a simple two−button PS/2 mouse designed to complement the company's early 1990s computers. While it lacked a distinct product name, the mouse carried standard Leading Edge branding and followed the familiar beige styling of the era. Internally, it relied on a traditional ball−based tracking mechanism and connected via the PS/2 interface, which had become the dominant standard before USB adoption. Regulatory markings and FCC records reveal its origins with a third−party manufacturer, offering insight into the sourcing practices behind Leading Edge's accessory lineup.

Leading Edge systems were frequently accompanied by a three−button serial mouse that reflected the transitional nature of early PC pointing devices. Although marketed generically and lacking a formal model name, the mouse carried standard Leading Edge branding and was sourced from an external manufacturer, as revealed through FCC registration records. Its ergonomic beige housing, mechanical ball tracking, and support for multiple serial communication protocols made it adaptable to a wide range of DOS and early Windows environments, even as software support for three−button operation remained inconsistent at the time.
