FWIW there was what must've been a 30" disk
platter
at the MIT Flea this weekend, mounted on its
center hub. Never saw a disk larger than 14"
before. Didn't get the manufacturer but the
price was $40.00 and the seller was Frank Fink.
Frank's alive? He owes my company money for returned
product for which he never issued a refund. I'd assumed
he'd died.
<sigh>
