The CC graphics I have reports
 Graphics Extension 2.09
The Acornsoft one
 Acornsoft GXR 1.20
in response to *HELP. Does yours?

Both provide graphics extensions such as circles and flood fills, the CC one
mainly through *commands, the Acornsoft ones through VDU sequences.

The Acornsoft one is handily forwards compatible with the Master, so much so
that with an ARM coprocessor attached to a beeb with the Acornsoft GXR in it
you can do
  CIRCLE 100,100,100
and behold a circle is drawn,
