While that was interesting, I wanted to try a different form factor, one that is closer to the original PalmOS experience. Up to now I have been calling it "PalmOS on x86", but there is nothing that prevents it from running on different architectures, so I grabbed a brand new 4GB Raspberry PI 4B.

For the display I chose one of those small TFT SPI based touch screens. I picked a 3.5″ model supporting a resolution of 320×480, which is perfect for this use case since later Palm handhelds with virtual graffiti used exactly that resolution.

All of them required installation of closed-source binaries and some would even overwrite critical files on the OS, like /boot/cmdline.txt, /boot/config.txt, /etc/rc.local and some others I can't remember now. Eventually I settled on this one:…
