I have GEOS for C64 and C128, and I'll be honest that I've never really given it the attention it deserves. My thought in picking up this book was it might finally give the motivation to really appreciate that GUI operating system for our beloved 8-bit machine.
The book was written in 1986 by Neil J. Salkind. Turns out he wrote a lot of books over the years, usually concerning statistics.
From About the Author in Google Books:
From what I've skimmed so far I'd have to say that's a pretty accurate description in his writing style.Neil J. Salkind is Professor Emeritus at the University of Kansas, where he taught in the Department of Educational Psychology for more than 35 years. His interest is in writing about statistics and research methods in an informative, non-intimidating and non-condescending way.
Interestingly, this book appears to have been written before the 1351 mouse was released. The text only refers to using a joystick or the 1350 mouse, which functions similarly to a joystick. I can't stand it unless I'm playing Marble Madness or something like that. But regardless, just thought that was interesting. The 1351 was released in 1986, too, but apparently not in time for the author to hear about it.
