@enkiv2 @ACE_Recliner@misskey.xyz @brennen @firstname.lastname@example.org I think MINIX always had 8-bit bytes, but yes, the original "Unix" ran on the 18-bit PDP-7, from 1969 to 1970. Eventually PDP-7 Unix did do multitasking, but I don't think it ever got, for example, a hierarchical filesystem. https://www.bell-labs.com/usr/dmr/www/hist.pdf is pretty much the only source on this kind of thing.
And yeah, the PDP-7 and PDP-11 were unrelated instruction set architectures.
