I would dearly love there to be a way to migrate A2D/Digital IO/RS485 comms ("DAQ") PCI interface cards to a VM. We've got a bunch of custom machine control software written in Delphi 7 that is almost impossible to upgrade because later versions of Delphi use Unicode strings which break the comms, the in-house author hasn't figured out to get around that, etc., etc. It runs Ok on Win 7 and should run on Win 10, but it's always a pain to get things reinstalled on moving to new hardware when a machine dies...

(sigh)

Cheers,
Scott.
