Actually the T800 overlapped acknowledge helps the unidirectional link
speed rather than the bidirectional speed.

I think that bidirectional speed is about the same, while the
unidirectional speed climbs from about 1.5 (??) to 1.7Mbytes.

T414 to T8 goes at T8 speed, T8 -> T414 goes at T4 speed.

C004s en route slow the speed by about 300K / C004.

Cheers,     Andy.
