There are other Alps PBT dye-sub sets, so all nubbinator really *needs* from the Wang is the delete, backslash, enter, right shift, and (ideally) spacebar and both sets of alt/ctrl keys.
Nubbinator: if you find yourself short any other keys (I don’t have a Wang 724, but I do have a few old Alps boards with PBT dyesubs), we can probably work out a reasonable price.
