@thalia The late Steve Hosgood built a (single-tasking) 6809-based 6th edition Unix "OMU" (One Man Unix), this might be interesting for the CoCo 3 port. OMU was later also ported to 68k-based systems.https://web.archive.org/web/20220826223815/http://www.pix.net/mirrored/discordia.org.uk/~steve/omu.htmlAlan Cox put up a copy of the tarfiles on github:https://github.com/EtchedPixels/OMU
