That seems to be the tricky part. I have a device that works with LabView but it seems really hard to find the old 68k Mac Nubus version.
I do have a vague notion of putting together a Nubus based lab bench for electronics work, and your cards would be ideal for that, MinerAl. Turn an old Mac into a software oscilloscope and logic analyzer, for example, and/or hook up any old laboratory devices that run on GPIB/HPIB. Build a robot. 3D printer. 68k home automation system. Control your garden sprinklers.
