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 never launched on devices and is no longer referenced on Access's website.
