   Core memory with an extra parity plane was quite common in the 1970's,   
   but I have not stumbled into core memories with ECC.   
      
   When semiconductor memory companies like Intel, tried to enter the   
   main memory business with 4 Kib, 8 Kib (partially faulty 16 Kib) and   
   16 Kib chips, which suffered from package alpha radiation, they had to   
   use ECC in order to reach similar reliability compared to parity   
   protected core memories.
