Very cool piece of tech (well, as long as the oil doesn't leak). DCS logic isn't really uncommon -- we just call it "LVDS" today.

Surely it must have been obvious by 1991 that they were sinking a fortune into a losing strategy. If the IBM brain trust had worked on improving CMOS processes instead, I've gotta think we'd be that much farther ahead.
