Don't forget Hauppauge i486 motherboard that had i860 on it. Not quite i960, but still RISC. Pretty much only thing you could do with i860 side was running sample application included on floppies that rotated some characters on upper right corner of screen - and that rotation persisted over reboot with ctrl+alt+delete. Whoo, multi-processing! I think i860 processor on that motherboard was intended to be used together with bundled non-standard display adapter for some sort of CAD use.
I actually had one of those, got it from some bankrupt company with full manuals, compiler for i860 etc. Shame I've lost it over years as I doubt there's many of those left today. Even had that custom display adapter and bunch of technical information from factory as it was some sort of pre-production sample sent to company importing Hauppauge products.
