I have owned 2 stand up video arcade cabinets.
The first one was a Galaxian machine. I completely restored it to original condition. Read about the restoration project on the GALAXIAN link.
When I finished restoring my Galaxian machine, I played it for a year, then sold it at an Arcade Auction. Read about my experience.
When I sold my Galaxian machine, I bought another Video Game Cabinet and converted it to a Mame Machine. Read a step by step account of how I made my dream machine!
