Nice TI99. 
What! No love for the Oddyssey 400?

The whole room has been a challenge. It's small, and it needs to house a pin collection, vid collection, and console collection. I'm fund-raising now for the built-in cabinets that will go in the corner for the TV and consoles. My built-in will surround a Cyclone pin cabinet stood on end with a drawer set built in to it for my consoles and a TV on top. I also have plans for a "raised" channel around the ceiling with arcade art and indirect lighting. The black and red colors will tie in to those elements, and hopefully tone down the floor a little.
The floor story is an interesting one. My mom works for a wholesale carpet company. The manufacturer of that VCT tile is changing the way the tiles are numbered. Mom's company had a cabinet with opened boxes of these tiles for samples, designated by this number. She calls and says they are going to throw away these opened boxes of tile, do I want some. I ended up going over and picking up all they had of the grey and red tiles. I then drew a floor plan in AutoCAD of my room and divided it up into 12" squares. I counted exactly how many tiles I had in the two colors, and came up with a pattern (yes, there is a pattern) that used those tiles, and then filled in the rest with black. It took two boxes of black tiles (with one piece left over) and all the reds and greys to do the room. $43 in total.
The VCT is great for the games because it is easy to slide stuff around (with the plastic feet, not the metal) and if a tile gets damaged, you can heat it with a heat gun, pry it up, and put a new one in it's place.
