my /23+ and /73. The /23 is limited to RL01/02.
Because unibus scsi controllers are hard to find (in my world) and
generally very expensive. Not to mention - sooner or later the original
scsi boards will die. It would be helpful to keep the machines around
longer if a "universal controller" existed that could emulate any of the
common historical controllers and storage.
When I contemplated this project, I was thinking of MSCP. But the other
day looking at one of my MicroVAX IIs (not Unibus of course) with an
idle KDA50, I wondered why people don't create faux-disks that emulate
the SDI interface. Not the same solution by any means, but are the SDI
controllers at least more common in QBus and Unibus setups?
Or, if recreating the controller rather than just an SDI disk, most
likely it would be simpler to emulate the KDA/UDA than MSCP?

I'm surely not the only collector who would be willing to pony up some
$$$ for such a project....
