Version history and technical background Manufacturers are free to implement different features of the OS in their devices or even add new features. This version history describes the officially licensed version from Palm/PalmSource/ACCESS. All versions prior to Palm OS 5 are based on top of the AMX 68000 kernel licensed from KADAK Products Ltd. While this kernel is technically capable of multitasking, the "terms and conditions of that license specifically state that Palm may not expose the API for creating/manipulating tasks within the OS." Palm OS 1.0 Palm OS 1.0 is the original version present on the Pilot 1000 and 5000. It was introduced in March 1996. Version 1.0 features the classic PIM applications Address, Date Book, Memo Pad, and To Do List. Also included is a calculator and the Security tool to hide records for private use. Palm OS 1.0 does not differentiate between RAM and file system storage. Applications are installed directly into RAM and executed in place. As no dedicated file system is supported, the operating system depends on constant RAM refresh cycles to keep its memory. The OS supports 160x160 monochrome output displays. User input is generated through the Graffiti handwriting recognition system or optionally through a virtual keyboard. The system supports data synchronization to another PC via its HotSync technology over a serial interface. The latest bugfix release is version 1.0.7. Palm OS 2.0 Palm OS 2.0 was introduced on March 10, 1997 with the PalmPilot Personal and Professional. This version adds TCP/IP network, network HotSync, and display backlight support. The last bugfix release is version 2.0.5. Two new applications, Mail and Expense are added, and the standard PIM applications
