This is a copy of the floppy that came with  the book "The Virtual Reality Construction Kit" written in 1994 by Joe Gradecki. ISBN: 0-471-00953-9

I can't express enough how great this was for the garage level VR enthusiast, at least in the mid-90's. All of chapter 2 is about different ways to hook up and use the Mattel Power Glove with your computer.
