I've come across my box of Palms a few times and had limited success getting them going. Seems they don't like being in storage for almost two decades. Really loved my Palms back then.
I have both a PalmPilot Professional (with serial) and a Palm m500 (with USB), the latter is a lot easier to pocket, but the USB support is horrible in modern OS. I keep wanting to get back in to Palm dev. I even managed to get Pila to compile under macOS Catalina a few years ago.
I also have a stack of V-Tech Helio's, which is a PalmPilot clone. I don't remember why I ended up with 3 of them, but I got them to reflash the OS and never got around to it. Their whole OS source code is available online. The compiler is not easy to make to work these days though. DJGPP and I think 16bit.
