Fear not...there are worth something (not much, but something).  Call metal
reclaimators.  They will pay for these parts to munch them back down to
their raw materials.

I used to work for a  drive company named Tandon.  They were at one time the
largest 5 1/4" floppy and hard disk manufactuer on the planet. We used to
obsolete ROMs like nobody's beewax and would be stuck with literally
hundreds of thousands of them many times a year (great MRP system, huh?).

We had every scrap jockey on the planet buying us lunch for the business.

BTW...Western Digital bought Tandon's hard drive division, where I also
worked,  along with Mr. Barry Klein.  Yes, THE Barry Klein. He's still
there.



I hope you didn't pay for these expecting Eproms tho!
