Of course I meant disk platters in working configuration as in disk packs
or stacks of platters on a spindle, not loose platers extracted from packs
or stacks and converted into coffee tables or wall ornaments.    :-)

 These same types of people vacuum up core memory boards, keyboards, disk

 Agreed for the most part, with the exception of disk platters.  While it
 might be theoretically possible to repair a disk pack, or disk drive, given
 a loose platter in good condition, I doubt this is practical.  Partly
 because few if any of us have the precision equipment needed to do this,
 and partly because loose platters are typically loose because they were
 wrecked.
 There might be some exceptions: a spare RF11 or RC11/RS64 platter merely
 needs to be bolted to the spindle hub and formatted, that's a normal field
 repair procedure.  But, say, a platter out of an RP04 pack is unlikely ever
 to be able to serve as anything more than a wall hanging or a prop.
