At a fleamarket I bought this little handheld computer called the Psion Series 5. It has backlit 16 level grayscale lcd with resistive touchscreen and a nice little keyboard. The reason why I bought it was that it has an RS232 port and pre-installed terminal emulation software. There is even a code editor on it.
The device is open to modifying the OS. Nothing is locked down as far as I know. I know people managed to install a linux distro on it. Mine still runs an early version of Symbian called EPOC 32 OS.

I think the pocket pc communities have scattered across the web, but recent projects involving the raspberry PI may blow new life into the pocket computer scene. If you know where I can find a pocket computer community on the internet let me know!

Thank you. It is a 32bit machine, so it's quite powerful despite it only running at 18Mhz. Back in the days people made games for it that you could buy. There are still some demo versions of those floating around as share/freeware. I might write an atari2600 emulator for it once I get the hang of programming for the EPOC32 OS.

COol machine.

I wonder what kind of games there are for it...
