I have an HP J2610A 10BaseT hub that I no longer need (except, perhaps, if I want to cause a serious case of the slows to my network). There are so many collectors of weird things out there...I wonder if I can sell it on eBay. Some years ago, I sold an empty HP21 calculator box (yes, just the box and manual) for more than $200 to a Hong Kong collector of HP stuff. I hope that I am that lucky again!
UPDATE: What the heck, I've listed it on eBay: starting bid, $5.
