With something like a PRM-85 and the 85B mass storage, E disk and
extended mass Storage you can support SS80 devices such as the 9122C. I
believe that the gentleman that created the PRM-80 distributes a
configuration for this exact purpose. When I had an 85A I created my
own card for these ROMs and others and made my design available.
