^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

It is almost as useful as the Fast RAM.  It won't be AS fast.  It steals
some of your working storage for the custom chips.  (But I still hobble
along with 512K CHIP RAM).  But it can still be used by the compiler and
other utilities.  The CHIP RAM is not exclusively for the custom chips; user
programs can be loaded and executed from CHIP RAM.

Hope this helps.  (I'm trying to be helpful, not nasty or critical).
