Default Re: Non-working Commodore PET 3016

The schematics (page 3) indicate that pins 3 & 4 go through "Cassette Jumpers" but having traced it on the board, they're not jumpers but four points in a square on the motherboard (marked in green on the attached photos).

Anyone happen to know anything about these?
