That was 100BaseT4 rather than the now more common 100BaseTX.  The idea
with T4 was to use cat3 wiring that "everyone" had in their walls.  Of
course the cards never took off since many people thought replacing
wiring and using only 2 pairs was much simpler.  That and T4 is half
duplex only which was really a deal breaker for many people.  TX grew
much faster than the T4 advocates had imagined and the prices dropped so
fast that T4 quickly died.
