**Osaris** is a [personal digital assistant](/source/Personal_digital_assistant) (PDA) featuring the [EPOC](/source/EPOC_(operating_system)) [operating system](/source/Operating_system) (OS) distributed by [Oregon Scientific](/source/Oregon_Scientific).[1]

The Osaris was released in 1999, and at the time priced at £219.99 (equivalent to £582 in 2025) to £279.99 (equivalent to £741 in 2025). The Osaris contains an 18.432 MHz CL-PS7111 (ARM 710) processor and is powered by two [AA size batteries](/source/List_of_battery_sizes) or an external power 6 [volt](/source/Volt) [AC adapter](/source/AC_adapter), with a 3 volt CR2032 cell providing backup power. The [liquid-crystal display](/source/Liquid-crystal_display) (LCD) is a [touchscreen](/source/Touchscreen), backlit 320 × 200 pixels with 16 greyscale levels. There are also 10 membrane keys, 5 on each side of the LCD. The Osaris can be linked to a PC via an [RS-232](/source/RS-232) link cable and [IrDA](/source/IrDA) (Infrared). The Osaris contains 8 MB of [read-only memory](/source/Read-only_memory) (ROM), and, depending on the model, 4 MB, 8 MB or 16 MB [random-access memory](/source/Random-access_memory) (RAM). The memory can also be expanded using [CompactFlash](/source/CompactFlash).

- Dimensions: 170 × 90 × 20 mm

- Weight: c. 250 g

After the debut of EPOC Release 5, the Osaris was the only PDA to use the EPOC Release 4 operating system.[1] It also has the distinction of being the first device to run EPOC (later renamed [Symbian](/source/Symbian) OS) that was not built by [Psion](/source/Psion_(company)). It is very similar in ability to the [Psion Series 5](/source/Psion_Series_5). The Osaris comes with these programs preinstalled:

- Agenda: For appointments, things to do, birthdays, anniversaries

- Data: For names, addresses, or other [database](/source/Database) use

- Jotter: For making quick notes

- Time: For alarms

- Calc: For simple or scientific calculations

- World: Shows a map, world times, dialling codes

- Word: For writing documents, letters

- Sheet: For tables, [spreadsheets](/source/Spreadsheet), graphs

- Program: Editor for writing [computer programs](/source/Computer_program)
