So to do that you have two project the hardware is

FYI I have never heard of any one recreating the RQDX1/2/3 software
protocol MSCP
as it was nontrivial, proprietary, and copyrighted.
Every time I thought about it, or even started, I gave up, because there
aren't simply enough people who would buy such a thing. The prices for
an old working Qbus SCSI controller are low enough, to just wait until
you get one on ebay for a decent price.
So all of my machines have SCSI in the meantime, and the headache of
making my own is gone ;-)
