I see the ULN2 is no longer listed on the MH site. Has it been officially discontinued? Any commitment re how long it will be supported? Just bought a 3d upgrade card last year, so hope it will be supported into the future.
It is officially supported for the foreseeable future; it is a full 3d unit and that is the core of the product line so software and driver support for ULN-2/3d is at the same level as all of our 3d-based units.
Certain parts that were part of the ULN-2 design have become obsolete, so it is being redesigned for future production.
