As loath as I am to plug my own stuff on the net, it might be a good
idea if you took a look at our Ocober issue; I did a piece on the
enhanced LocalTalks.
 
The quick answer to your question is that non-Mac LocalTalk devices
can't be used at enhanced LocalTalk speeds, unless they specificically
support enhanced LocalTalk. I can't think of anything out there that
does this. StarControllers will work, but that's about it (as far as I
can remember).
 
Non-enhanced nodes usually can't see when enhanced nodes are
transmitting, and will therefore step all over enhanced traffic. This,
obviously, messes things up a bit.
