One day I turned my monitor on and it started flickering really quickly. After around 30 seconds or so it would come right until I turned it of again. I didn’t get a video of it but it was the same as this video. I have had the monitor for almost ten years, so I am not surprised to see it begin to die. After leaving it for a few days and then finally got around to looking up the problem.

Zero Tolerance is first person shooter for the Sega Mega Drive that supported multiplayer via a system link cable. However this system link cable is rare and difficult to find as it was sold separately.

I saw an Atari 7800 for sale on TradeMe and I had never owned one before, so I decided to place a bid of $95. It came with 3 paddle controllers (only one had the ‘knob’), a two button Atari controller, power supply and the game cart Combat. The game also had the manual and box but the box has seen better days.

I picked up a broken model one Sega Saturn that from the description of the auction suggested that only the fuse was blown from plugging in the wrong voltage. In New Zealand our mains power runs at 240 volts and this was likely a US console that runs on 110 volts.

I picked up a Master System 2 cheaply and since it only supports RF as the video out I thought I would have a go at modding to support at least composite video out. The version I had used the Sony CXA1145 video chip. This seems to be a fairly common video chip found in a few consoles so it is well documented on what it does. On the SMS Power forums I found the following schematic:
