I use the voice memo recorder to record rehearsals and listen back to them on my iphone, its awsome
Bt, i would LOVE that, i'd be ever so grateful for the tapes, and i'd love to hear whats on them!! If you want i could rip whats on them and send it to you?
I'll PM you my address

I'm sorry jamessss...I am getting old and forgetting where everybody is...thought you might be in the US
It would likely cost me waaay too much to ship some tapes across the pond, but you can probably find some unused DAT tapes if you scour the bargain bins of pro audio shops/websites. Last DAT tapes i bought about five years ago cost like $1 ea (compared to $10 ea when it was the popular format).
I'll keep my eyes peeled for bargains and direct you to them tho
EDIT: here's one lead...
