Sejin Electron SPR-8695TU Compact Trackball Keyboard

Sejin Electronics SPR-8695TU is a compact 86-key keyboard with an integrated high‑resolution trackball, designed to fit tight workspaces while preserving precise cursor control. Its footprint measures 292 mm wide by 142 mm deep and 30 mm high, with a full-size 19.05 mm (0.75 in) key pitch for a familiar typing feel. The trackball is engineered for high precision and contaminant resistance, and the keyboard features an inverted‑T cursor keypad along with separate Insert and Delete keys for quick navigation. A non‑skid rubber base helps keep the unit stable during use, and cable configurations include USB or PS/2 options depending on the variant. The SPR-8695TU is electrically compatible with IBM PC/AT and USB systems, supporting classic PC keyboard functionality and listing 86 keys in its main layout. This Sejin compact keyboard combines typing input with an on‑board pointing device in a single chassis, making it suitable for setups where desk space is at a premium and a traditional keyboard would be too large.
