Once again, I’ve failed to accomplish much during the month-long celebration of Retrocomputing. My Apple ][ programs can simulate simple ballistic motion and orbital insertion, but fail miserably when trying to realistically simulate Earth Orbit or (an order of magnitude harder) a transfer from Earth orbit to lunar orbit. I can safely say I’ve reached the limits of my own understanding, if not the capability of the Apple ][+!
Looking at the other entrants, I’m amazed (as always) at both the breadth and depth of retrocomputing as a hobby! Good luck to the judges when it comes time to pick a winner!
