The Treo 90 is a Palm OS PDA developed by Handspring. It was released on May 28, 2002. The Treo 90 was the only Treo model produced without an integrated cellular phone and was the first model of the Treo product line. When first released it was the smallest Palm OS device on the market.
[edit] Design
The Treo 90 features a 12-bit standard (160x160) resolution colour super-twisted nematic display, LED backlighting, a miniature QWERTY keyboard that replaces the usual Graffiti on other PDAs, an infrared port and an SD card slot.
[edit] ROM Update
The original Palm OS (4.1H) lacks SDIO support and reportedly has trouble formatting 128 megabyte SanDisk cards. The Treo 90 Updater addresses this problem and adds some other edits. The update is not a software patch but is burned into ROM.
