"That was a heroic effort!"
Gauntlet's technology was a big deal in 1985. My nerdy friends and I had never seen the likes of it and spent hundreds of dollars plodding through the levels. At one point a friend had a small arcade in his shop with a leased Gauntlet and a couple of other games. One night after hours we picked the locks on it--not to steal the money, but being the geeks we were, we wanted to have a look at the silicon to see how much hardware was crammed into the cabinet to provide this level of gameplay. As I recall, we might have adjusted the skill level a bit to give ourselves a better chance. It was easy when coin-ops of the 80s usually came with technical manuals and operator instructions lying at the bottom of the cabinet. :)
Gauntlet IV on Sega Genesis was a pretty good clone, and "Dark Legacy" on PS2 was enjoyable. But I still like firing up MAME/MESS and taking a run through Gauntlet I and II when the mood hits me.
