    Apparently, there is no service manual for the 570, or they are
extremely hard to come by.  Programming wise, the 570 is identical to the
CDTV, which is very close to a 500.  The CDTV libraries, by Carl Sassenrath
of CDXL fame, is placed into the system via a ROM patch-this is put in on
boot up.  It ensures CDTV compatibility.

    There are many who are working on the 570.  Some of the people
below are interested in learning and programming this device.
