For my beta DM41X calculator, I made a quick Powerpoint alpha legends backside. It's a stopgap, of course, because eventually I will give in as well, and order a production DM41X for myself
For the time being, I just taped over it with (ahem) "invisible" tape. Probably looks much better when you laminate it.
