In March 1999, Sharp launched a new line of mobile computers branded Telios. This included three devices: HC-AJ1, HC-AJ2, and HC-AJ3.
These first-generation Telios devices all feature and 8.4-inch display with a resolution of 800 x 600 pixels – an industry-first colour transflective TFT display capable of reproducing 65,536 colours.
The Telios are powered by a 129 MHz Toshiba TMPR3922U processor (already deployed on the Mobilon Pro PV-5000). Each instalment in the series comes with more RAM and ROM (read below).
The Telios measure 213 × 192 × 24.2 mm and weigh significantly less than their Mobilon predecessor – just 810 grams!
The Telios computers can reproduce stereo sound – but only on headphones; the built-in speaker is mono. An optional accessory is the LCD-display headphones (3.5 mm audio jack!), which allowed reading incoming email without opening the Telios (only on the HC-AJ2 and HC-AJ3).
Further innovations include USB 1.1 connectivity and a built-in microphone. Another notable upgrade from the Mobilon series is the addition of IrDA connectivity and the ability to play back MP3 files.
