The Swedish computer club #PD68 built Motorola 6809 and 68k-based systems in the 80s. One of these systems, based on a 68k-based CPU board designed in Norway, runs the Idris OS, the first Unix clone.

I’ll give a talk on Idris and the PD68 machine next SATURDAY (April 11) – not! Friday as I wrote – at 19:00 at Update dataföreningen in Uppsala. I‘ll show the (non functional) PD68 machine and an Atari ST emulator running Idris!

Technically Idris was explicitly not a Unix "clone" because they were concerned about violating Bell Labs copyright on the Unix Programming Manual, and made many small changes to make it clear that it was a separate language and operating system. For example they replaced printf with putfmt...

This is not to say that Idris was not amazing.
