It's one of innumerable nameless clones that were made (likely in Taiwan) of the II+ motherboard and ROM, with the slight change of banner from "APPLE ][" to "NEW DATA". Some clones were made by legitimate means (B&H, Basis 108, Laser), some were on the ragged edge (Orange, early Franklin) and some were out-and-out theft and duplication of intellectual property (your clone and many like it).
