I think I still have a Bernoulli Box (one of the smaller 44MB cartridge models) hiding in the closet behind a box of random tangled cables and other ephemera. It would have moved twice with me since it was last used.
It's in the huge mound of electronic waste waiting to be hauled away. It was given to me by a tax preparer in lieu of payment. Never did work for that guy again. Tax preparers are really cheap. Doctors, at least, will eventually pay you. Lawyers, of course, never pay, "So sue me".
