Parity?
I recall a talk on the early Cray 1 computers. They were originally designed with only parity, but soon (after experience with the "production" use of Serial #1) switched to ECC. Serial #2 was too far down the assembly line to be worth the retrofit and was scrapped. All later systems were a bit taller than #1, to accommodate the ECC mod.
(I assume the case of Leinenkugel beer intended for shipment with #2 was properly disposed of :-)
