Hi Audrey - Thanks for your suggestion which is valid - I have the 720MB floppies which have been formatted correctly, two came with the organ and a fellow forum member has kindly let me have some more.

To compensate for the lack of information in the manual what I need is a hand coming out of the organ and a finger pressing a certain part of the organ and a message saying "Press This Key"

How many times have any of us been using a any sort of equipment be it PC or other when this sort of message would have been a godsend? Joan
