You want the 6944, other than needing the reverse probe option in
the tulip driver they just drop in. I have three in production use right
100Base-TX is a 2 pair 100Mbit ethernet, uses the same pair scheme as
10Base-T. 100Base-T4 is a 4 pair 100Mbit ethernet spec. Never widely
used, and (IIRC) was designed to run 100Mbit ethernet over lower grade
cables. As cat5 cable became easily available it fell from favor along
with 100AVG AnyLan stuff.
As folks might have suspected, not much survives except roaches,
and they don't carry large enough packets fast enough...
