 What kind of DMA though: ISA bus mastering or the Intel 8237 data mover? 
Or neither?  Either way, quite disappointing -- it all should be pretty 
easy to reproduce with modern circuitry.

 The software side is another matter however -- x86 real-mode OS drivers 
should be easy to run virtualised, but other environments are a tad more 
difficult to emulate.
