Only time I ever won some solid cash ($2.4k) in Vegas was on this back in 2007 at The Excalibur fucking around killing time before a show. Except it was on a dollar machine.
We had a trash80 model 4, too. Playing Zork on it when I was 13 was the first time in my life I gamed for 30 hours non-stop with no sleep. Spy Hunter was pretty cool.
