I wonder if there's any way to track DMA calls. Of course part of the point is that the 8088 is out of the loop... In any case, I don't...

I suppose without access to the ISA bus signals not tapped by the 8088 you'd need to trap writes to the I/O ports for DMA control registers and channels 1...

Related - I've just clocked that the various bits of runtime (mode==1) conditional code in the accelerated version are commented out. It looks like most of that is about ROM...
