Interesting (old) VR book

I found this randomly at a book store in Maine. It was an interesting read from the immediate pre-Virtual Boy era (~1993). There was a pretty good description of other VR systems at the time, with a neat list in the back of the day’s main VR software/hardware companies. My hope was that there would have been some mention of Reflection Technology working on a crazy new display, but sadly there wasn’t.

It does mention the Sega Master System 3D glasses though, with a circuit to connect to a PC’s serial port I think.
