        I think he's talking about using the raw core plane, so at that
      level, there's effectively no difference.

      when I took a closer look, it does appear to be a raw core plane - is that PG-rated ;)
      As there's no support logic on there that you typically see in a memory controller circuit. Other than what appears to be some kind of buffer or level translator chips sparsely located on the edges of the core and routed to the backplane card edge connectors.

      This is a common approach, as even the old systems I worked on used a stand alone memory controller card and individual cards with core memory and the bare essentials.
