I wrote these as part of my work on the Leeds university domesday 
emulator. It has a few things hacked into it (like video commands) but 
they are easily removed. It also needs either the data register read or 
write operation (can't remember which) modified to invert the bits, as 
the SCSI "adapter" in the domesday box used a different chip for one of 
the data register buffers to that on the hard drive SCSI adapter.

If the current BeebEm maintainer would like these (and they are tested), 
please step forward....
