Did you write code for #Psion machines in the #80s and #90s?
We're calling for you to open source your code!
I'm working with a group of enthusiasts, building a library of information about the SIBO/EPOC16 platform. Your old code could give valuable insight, as well as encourage people to write new code.
We're especially interested in old C and #x86 #assembly.
Upload it to your public repository of choice, and set it free!

How do you manage to get out the drafts from it? Serial interface to a modern computer or else?
@magnetic_tape @kaleissin Usually serial with a USB-RS232 adapter. Either PsiWin on an XP VM, Psion MCLINK in DOSBox, or plptools on Linux.
I can also dump the contents of an SSD with a Raspberry Pi Pico or Arduino Uno, then extract the files from the volume with a C app I've written.
@magnetic_tape @kaleissin Yep!
This is the code for the Uno (uses PlatformIO): https://github.com/PocketNerdIO/libsibo
This is the app that calls the Uno and dumps the volume: https://github.com/PocketNerdIO/sibo-ssd-dump
And this extracts files from the dumped FEFS volume:

The packaged releases might not be the latest versions, so compile with Git if you can.
You can use libsibo with a Pico, but it needs level shifting between 3.3v and 5v. I'm working on a PCB that has all the circuitry needed.
