Or, umm, *I* have a trash bin and if you'll send it to me, I'll get rid of it FOR you... yeh, that's the ticket...
Seriously, if the calc is dead, parts of it may help others here-- offer it as is. If it works, but has flaws, such as a bad power switch, a few of us may want to try to repair it for ourselves. Sell it. If you only need batteries, heck, that's not an insurmountable obstacle... and you may want to even do it yourself.
A 34c is a good calc for students especially-- though it has no I/O or cards, it IS programmable and RPN (two addictions that ought to be fostered).
Just don't feel like an HP calc is too old or a hopeless throwaway-- if there's any thing we know from experience, it is that the newest models ain't perfect, either....
Recycle! :-)
