Sometimes the internet amazes me. They're in the process of scanning in Polyphony back issues. I had to manually edit the URL to get this one or else I missed it in the menu. https://www.muzines.co.uk/images_mag/pdf/pl/pl_84_04.pdf Anyway short version is in 1988 I got sucked into making this project which was a MIDI keyboard controller. So first I called down to the Rockwell brick and mortar that was in Atlanta where I lived at the time (1988). He said come on down. I got there and the guy came right out, didn't want me to come in but he handed me a jewel case with two virgin 6511's pressed into antistatic foam. I only asked for one and was prepared to pay $. That made a big impression on me that day, that someone would do that. So I said to myself I have two so maybe I ought to get parts for two projects. So I got two circuit boards and two proms with the software loaded from Kirk (I assume). I did eventually get one working all the way. The twist to this story is 35 years later I still have the other 6511 and the other prom in the Rockwell jewel case and the second circuit board.
