[Coco] 512K AND Beyond??? How FAR Beyond???

[Richard Cavell]

   I think that page needs to decide whether it's 512 MB or 512 KB that is
   being added.

   And the electronic issue that you describe doesn't stop the scheme from
   being successful. If I'm not mistaken, you could add arbitrary amounts
   of memory in this way.

   You are describing MOOH:

   There are problems (If I remember correctly, you can't prevent writes
   to
   internal RAM from occurring if you write to external RAM, though you
   can
   prevent internal RAM from being read - via the SLENB line).
