My experience is that tapes of that vintage are usually still playable, at least if they've been stored in good conditions. The binary data is generally encoded as a series of long and short square waves, so you can often recover the data even if there's quite a bit of noise. Personally, I've successfully archived Astrocade tapes from as long ago as 1979.
