At the moment my collection is somewhat thin after having owned in excess of 30 machines at the peak of my collecting craze. I sold the vast majority of my collection recently including many of the spare parts I had in the attic.

I do have a tremendous number of original ROMS and EEPROMS I have collected over the years that are all readable on my ancient 80's era EPROM burner. I've even read semi-damaged EEPROMS and dumped them into MAME to watch it reproduce the real machine's flaws in the emulator. Now that's accuracy. :)

At the moment I own these remaining classics:

• Pac-Man (Midway)
  
• Millipede (the basis for this MAME project)
  
• Marble Madness (with Peter Packrat and Road Runner)

• Road Kings
• Space Station

At one point in time I owned these machines:

• Burgertime
  
• Centipede
  
• Dig Dug
  
• Joust
  
• Crystal Castles
  
• Space Duel (cocktail)
  
• Mr. Do's Castle
  
• Elevator Action
  
• Tron
  
• Gauntlet
  
• Q*Bert
  
• Frogger
  
• Donkey Kong / Donkey Kong Jr.
  
• Defender
  
• Super Mario Brothers Vs. System
  
• Congo Bongo (cocktail)
  
• ...quite a few others I can't recall at the moment...
