What makes IDE
to Qbus or Unibus interfacing so difficult? There must
be reasons, otherwise it would have been done by now.
Lack of driver space in the OS is my guess, looking at the PDP-8.
There you had just one or two pages for the device driver. 256 words
might be the limit of code space permitted.
