As far as I can tell, all the slots will check if PRSO has KEYBIT when you try to put something in it. If it doesn't, it won't fit. All, that is, except for the red slot:
>PUT SPACE SUIT IN YELLOW SLOT
The space suit doesn't fit in the yellow slot.
>PUT SPACE SUIT IN FIRST RED SLOT
The space suit slides into the slot and disappears.
These two cases are handled by YELLOW-SLOT-F (correctly) and RED-SLOT-F (incorrectly).
(Incidentally, it works even if you're wearing the space suit.)
