Re: HP 65/25 shout-out in interview with Paul Lutus Message #3 Posted by ClausB on 21 Dec 2012, 8:50 p.m., in response to message #1 by Egan Ford
In 1977 I was looking through my local library for anything about microcomputers and came across an article in Popular Electronics by Lutus describing his game program Space Flight for the HP 25. In the game you control the thrust of a spacecraft orbiting two planets and try to land on one. A 2-D, 3-body lunar lander game!
I wanted to play it on my shiney new SR-56 so I taught myself RPN and converted it. What fun! I still have my listing and a photocopy of his. To compare: the 25 version uses 49 steps and 7 registers; the 56 version uses 92 steps and 10 registers.
Last year I emailed Paul and reminded him of that article. He said he wrote several popular articles back then. I encouraged him to post to this forum but I haven't seen anything.
