can anybody use these tapes?

In among a whole bunch of audio tapes are these three "Teac CT-500H High Density Magnetic Tape Cassette"s... Instead of the usual tab that you can break out to prevent recording there's a small red bit in one of the holes, which the bit of paper in there refers to as a "write enable plug". Two of the three are still sealed in their original plastic. I don't think even the third one is used at all. Feel free to contact me offlist if you have any use for these... -- Member of the toughest, meanest, deadliest, most unrelenting -- and ablest -- form of life in this section of space, ?a critter that can be killed but can't be tamed. ?--Robert A.
