Access Co. in the context of Samsung

Palm OS (later versions of which were also known as Garnet OS) is a discontinued mobile operating system initially developed by Palm, Inc., for personal digital assistants (PDAs) in 1996. Palm OS was designed for ease of use with a touchscreen-based graphical user interface. It was provided with a suite of basic applications for personal information management. Later versions of the OS were extended to support smartphones. The software appeared on the company's line of Palm devices while several other licensees have manufactured devices powered by Palm OS.

Following Palm's purchase of the Palm trademark, the operating system was renamed Garnet OS. In 2007, ACCESS introduced the successor to Garnet OS, called Access Linux Platform; additionally, in 2009, the main licensee of Palm OS, Palm, Inc., switched from Palm OS to webOS for their forthcoming devices.

The Access Linux Platform (ALP) is a discontinued open-source software based operating system, once referred to as a "next-generation version of the Palm OS," for mobile devices developed and marketed by Access Co., of Tokyo, Japan. The platform included execution environments for Java, classic Palm OS, and GTK+-based native Linux applications. ALP was demonstrated in devices at a variety of conferences, including 3GSM, LinuxWorld, GUADEC, and Open Source in Mobile.

The ALP was first announced in February 2006. The initial versions of the platform and software development kits were officially released in February 2007. There was a coordinated effort by Access, Esteemo, NEC, NTT DoCoMo, and Panasonic to use the platform as a basis for a shared platform implementing a revised version of the i.mode Mobile Oriented Applications Platform (MOAP) (L) application programming interfaces (APIs), conforming to the specifications of the LiMo Foundation. The first smartphone to use the ALP was to be the Edelweiss by Emblaze Mobile that was scheduled for mid-2009. However, it was shelved before release. The First Else (renamed from Monolith) smartphone, that was being developed by Sharp Corporation in cooperation with Emblaze Mobile and seven other partners, was scheduled for 2009, but was never released and officially cancelled in June 2010. The platform is no longer referenced on Access's website, but Panasonic and NEC released a number of ALP phones for the Japanese market between 2010 and 2013.
