Never saw one, never played one and never even heard of one until I went on my second arcade road-trip ever back in 2004. I was picking up a vs. Dr. Mario for my wife just outside of Milwaukee. It was an eBay auction I'd won while I was vacationing in Hawaii. I was so stoked because the seller had a pic of a PC-10 conversion in a DK cab in the auction listing. I was new to the hobby so after staring at the pic for a while I decided to research the PC-10 a little. When I found out you could have 10 games in the machine at one time I almost shit my pants. I get there and the dude leads me to the upstairs of an old dilapidated stand-alone garage. In fact, as far as I remember, it was the only thing on the lot, there wasn't even a house. Anyway, we get up there and I stood there in disbelief. I looked around and all I could see was garbage everywhere, dirty clothes and rags all over, and on and around 2 or 3 rat infested couches lay hundreds if not thousands of porno mags as far as the eye could see. After my eyes re-adjusted and I stopped shooting loads into my pants I was finally able to see several beat up arcade machines sitting against the wall around the room. There was a Hang-on, the Dr. Mario and a few other conversions. I walked up to my new Dr. Mario and said, "WTF is this? I thought I bought a PC-10?" "Oh no, this is just a regular old Dr. Mario," he says. "But the pic" I said, "The pic in your auction was of a PC-10." "Oh yeah," he says "I forgot. I was just trying to give the buyer an idea of what he was getting." I'm like, "huh? That pic looks nothing like what I am getting" Then I take a closer look at the machine. The bottom was rotten, the cab sides were rotten about 12" up and the machine needed a serious cap kit. No wonder he didn't take pics of the actual machine for the auction. Oh, did I mention that the auction had a BIN price of $350? Yeah, cuz that's the price I agreed to pay, before I knew what I was actual buying. Anyhoo, we started talking a little about the merits of the PC-10 system when he says "Oh, but you know the NEO GEO was a much better multi game system." I was like "OK, W-T-F is a Neo Geo?" He then keeps making exclamations and comments like: "You seriously never played a NEO GEO?!" "Seriously, who never heard of the NEO GEO?" "Come on, you played one, right?" "Please tell me you're kidding?" "What moron has never heard of the NEO GEO?" So when I told him "this moron", he then tried to explain the system to me. I didn't get it then, I don't get it now. I never played one, don't own one and because of that one incident, I will never have one and will forever hate the "NEO GEO."
