I think this record is erroneous and should be removed. I do not recall writing this book. I had written Personal Graphics for Profit and Pleasure on the Apple II Plus Computer, and Personal Graphics for Profit and Pleasure on the IBM Personal Computers with my son Graham. The PC book contained much more material than the Apple book, and the publisher may have intended an Apple book that matched. I do not know if this could have led to a premature announcement and assignment of ISBN. I have checked with the publisher but, given the passage of time, that has not clarified.
