There is an OMTI RLL AT HD controller (model ?) that clams to do this. In
fact I was down at Sunnyvale Memories and seen it running on a 10Mhz AT
clone. 485Kb a sec. I just talk to them recently and they said there was
a bug in it, and that the new model should be in about a months time.
The benchmark used was Coretest.
