Here is a zip file with all my collected data on the Power Glove. They were spanned over five floppy disks, unfortunately some data was corrupted, and I do not think the instructions for hooking the power glove up to the parallel port is in here. Though there is one for hooking it up to your keyboard port. I used Joe Gradecki's book for hooking mine up.
