Jerome Fine replies:

But have you tried to get an IDE drive to work with a Qbus? That would seem
to be an even better goal? Well at least from my point of view! I do admit
to being strictly focused on a PDP-11 as well. I always wondered why none
of the 3rd party manufactures did not do an MSCP emulation. And if you are
still concerned about using MSCP until or before the patent expires, there are
a number of other possibilities that are much less difficult and still allow
a 32 bit block number. Can you at least suggest how easy or difficult it
might be?

Sincerely yours,

Jerome Fine
