Atari 800XL Remake
For my 55th Birthday last summer, I pulled my original Atari 800 out of storage and played Star Raiders and MULE non-stop for a weekend.  Great fun.  The most challenging part of getting the 800 running was finding an old enough TV that I could connect the game box too.I also couldn't get my 810 disk drive working, so I found a copy of MULE on eBay burned on a ROM, so that was a nice find.Great old machine, I think I'll buy one of these, the addition of HDMI and USB alone are worth it.  Plus it'll be fun to write a game on that thing, something I dabbled in as a kid and was my start as a programmer so so long ago now.
