I'm flashbackmatt on AtariAge. I think I sold you Pac-Mac Collection for the 7800, and a couple of other things.
My electronics repair success rate is not great. I tried to resurrect a XEGS, failed, and gave that away. The light sixer just needed some solder reflowed, and I need to fix the difficulty switches next.
My biggest success was putting this together without burning or shorting anything http://www.morserino.info/ I got rid of most of my ham radio gear, but kept that in case I ever get around to learning Morse Code.
It does go by way too fast. I take lot of photos, and my wife takes more videos. Now the kids want to take photos with the phones, and occasionally with the TLR or my mirrorless cameras.
