RE: 28 Battery door needed
Did you look at illustrations for changing the batteries on pages 287-288 of the HP-28S Owner's Manual? They are pretty good.
The tricky thing about putting the cover back on is that you have to press down on the batteries while you slide the cover on. It is truly a terrible design.
