Osaris is a personal digital assistant (PDA) featuring the EPOC operating system (OS) distributed by Oregon Scientific.
The Osaris contains an 18.432 MHz CL-PS7111 (ARM 710) processor and is powered by two AA size batteries or an external power 6 volt AC adapter, with a 3 volt CR2032 cell providing backup power.
The liquid-crystal display (LCD) is a touchscreen, backlit 320 × 200 pixels with 16 greyscale levels.
The Osaris is the only PDA to use the EPOC release 4 operating system.
It also has the distinction of being the first device to run EPOC (later renamed Symbian OS) that was not built by Psion.
