[Simh] Raw access to disk/cdrom devices

[Christopher Cureau]

I was thinking about how difficult it would be to add support for accessing
physical devices from simh.  My idea was initially to add support for a
SCSI controller in the pdp11 simulator and then add the code to have it
talk directly to either a physical SCSI card in the host machine or to the
individual devices.  I'm not sure how os-independent this can be, however.
Has anyone else had any thoughts about how this could be implemented?
