Really awesome to see this working, including the little LCD screen that occasionally has fun messages on it during gameplay. The only thing missing is the little sound effects based on joystick presses (also a little chime when you pass a time zone), but maybe that's handled through some other method inside the cabinet.
Sega went on tour back in the 90s, mainly to promote the Genesis (or was it Master System?). Anyway, they brought along a Time Traveler machine but set it up at kind of a distant corner of the mall food court - Southland Mall in Hayward if anyone's wondering. Anyway, about 5 or 6 kids hung out with the Sega rep and took turns playing free games. I actually got to appreciate the game and how to clear some of the levels - though none of us could get through the last stage. Anyway, it actually does vary the levels a fair amount each playthrough and has a lot of strange and quirky moments. But, at 75 cents, this game didn't get much play and was usually the rarely-touched novelty in arcades.
