For the present purposes, I'll say that as a 76-year-old, approaching retirement, I am developing a pretty nice music composition studio, with numerous of the latest and quite amazing sound generators. I'll be glad to send jpgs to anyone who might be interested, when (literally) the dust has settled. But I cut my music-making teeth using an Atari 520-ST which I'm currently striving to resurrect without a lot of success. The floppy readers don't seem to hear the call to action. I'll update this as appropriate.
