Legacy Portable Computing Wiki (LPC for short) is a wiki that intends to document and preserve knowledge of primarily older mobile devices.
The idea of the wiki was largely inspired by "Cell Phone Knowledge Base" (CPKB wiki) but that wiki seems to be effectively closed as you can no longer create an account on the site and the last dates of activity seem to stop around 2014. Not only that, but as a resource it isn't very helpful considering that the majority of the links to service manuals and phone firmware are broken.
Preservation of old mobile phone stuff was scarce for a while, with lots of links to firmware and service manuals being lost to time because the file hosting services they used don't exist anymore, or something happened that caused the files to be deleted.
This wiki should help to change that while being a less temporary destination for those resources.
