Running a full Debian distribution on handheld computers
PocketWorkstation runs in a chroot environment on a storage card, using the vendor's preinstalled native Linux system for most hardware access. GUI is based on Xf4vnc and the fbvnc framebuffer viewer.
Runs on Sharp Zaurus handhelds: SL-5x00, SL-6000, and the clamshell models SL-C7x0, SL-C8x0.
