Trying to FIX Astro Wars & FIREFOX F-7 table top 1980s games.

Hi, this 'trying to fix' video shows me attempting to repair 2 Grandstand table top games from the early 1980s. These belong to my friend Huw and have been stored in his mums attic for the last 20 years. They both had their batteries left in them when stored and they leaked very badly over the years. He tried them with new batteries and they didn't work, so he asked me if I would like to film the attempted repair. I attempt the Astro Wars first and then at 30:02 I attempt the FIREFOX F-7. Remember that this is just for entertainment and I am not an expert in these repairs. The processes in the video may not be the best way, the correct way or the safest way to fix these things. I do love fault finding and trying to fix broken things so I hope that comes across in this 'Trying to FIX' series. Many thanks, Vince.
