Tape. That's how I used the Orch90 cart before I got a disk drive so I could have stereo dacs. Any tape residue can be cleaned up with acetol or alchohol.

Oh, and to open the carts, on the slot side, there's a "pin" on each side. Just press the top or bottom (can't remember) inward very firmly and it will release. Sometimes one will pop off, but you still have the screw to hold it on reassembly.

A long time ago, I just used scotch (cellophane) tape to cover the pin of
various cartridges I wanted to dump.  After removing it, I didn't have any
significant trouble cleaning the contacts (and my cartridges and cartridge
slots still work), but your mileage may vary.
