You could verify that the other slots work by seeing if a Rompak will
execute after poking the slot number into $FF7F.

POKE&HFF7F,&H00 for slot 0
POKE&HFF7F,&H11 for slot 1
POKE&HFF7F,&H22 for slot 2
POKE&HFF7F,&H33 for slot 3

(regarding the slots as numbered 0-3 rather than 1-4), followed by
EXEC&HE010
to jump to the Rompak.
