I think this is for the PS/2 as marked by the N1 image having a PS on it...

Also I was unable to de-compress 021.SCO_XENIX_OS__BASIC_UTILS_____REL-2.2___MEDIA-35DSDD__TYPE-N86___ID-018.22B.000.16218_VOL-B1___3.5FLOPPY720K.bz2

I'm pretty sure this is the one that was fixed up and documented on http://os2museum.com/wp/ however that site is currently down.
