Arcade machine...to gut or not to gut. that is...

I worked for an amusement and ATM company for about 5 years. I've scrapped quite a few old arcades, cranes, ticket games, and atms. Like the previous members said....mainly boards with a lot of IC chips, CRTs, and wires. Some arcades actually have game cartridges like the old Nintendo's that plug into the board. These can be quite valuable. I remember scrapping out several Metal Slug arcades and selling the cartridges on Ebay for around $100 each. Good luck!!
