Not sure if these are compatible with modern laptops (they were not compatible with mine), but I have:
1) One Targus cable with a combo lock (I do not have the combo to unlock it, but there are only ~10,000 possibilities to try, I think)
2) One cable with two keys
Generally available during normal business hours (Monday through Friday, 9 AM through 5 PM; not available on weekends). If you would like the items, please email two time windows (including which day) that you can come during normal business hours.
If this post is up, I most likely have it.
