I think 10MHz is "very fast" for an isolated bus.  But that's not
really what you mean, is it?  You have the 80c188 (high integration
version of the Intel 8088) running at 10MHz and you want to connect
it to some peripheral in an isolated manner?

IIRC, the x88 has bidirectional databus, which will further complicate
things...
