Retro Computing

I sometimes see retro computing posts online. I have no interest in old Commodore 64s, Amigas, or game consoles. But a while ago I bought a second hand Palm m105 and reminded myself how much I used to love mine.
When they were current, I badly wanted a Psion series 3 or 5. I recently managed to get a series 3 and a 3a for reasonable prices. They’re impressive machines, especially considering their age.
If I can get a serial cable for the Psion, it will be interesting to work out how to copy files between them and my Linux laptop. I might then experiment with using one as a writer deck. Or I might try writing something in OPL, the Psion’s built-in programming language.
