Evergreen Systems International manufactures high-resolution industrial / military grade trackball pointing devices. A wide variety of desktop and panel mount trackballs or trackball assemblies are available. NEMA 4 and non NEMA 4 keyboard trackball assemblies are available in a tabletop or a panel mount configuration. These devices replace the mouse in computer systems where rapid, accurate pointing functions are desired (CAD / CAM, graphics, workstations, kiosks, etc. ) , and in industrial / military computing and control environments where a mouse cannot be used due to space limitations, harsh environments, or other factors. Evergreen units interface with SUN, DEC, HP / HIL, IBM, SGI and Macintosh thru USB. Custom Design is available. All Evergreen products are manufactured in the USA at our plant located in Camarillo, California.
