Not really much to say about my game other than I bought it at an auction locally at the same time I bought my Circus Charlie. I bought it because the price was right and the monitor was bright and crisp and had a cap kit recently done to it. It was however missing the glass bezel when I bought the machine. A member on BYOAC was looking to MAME a Dig Dug cabinet the guy was in TX and was hesitant about sending the glass bezel because he didn't want it to break during shipping, but I received it with no problems. I went onto mikesarcade website http://www.mikesarcade.com/arcade/artwork/ataricoin.pdf and printed out Atari Coin Door Inserts which look pretty neat. Below is a picture of my Dig Dug cabinet. In terms of restoration I really didn't do much with this game, I think to date it's likely the least amount of money I've ever put into a game. But it still plays and looks fantastic. Dig Dug certainly has it's fan base, many ports throughout various consoles along with mobile versions of the game still exist today even after 30+ years It's still a very popular game today.
Here is the review for Dig Dug, from the June issue of Computer+Video Games from the year 1982.
