I saw very few TV Dice in Las Vegas. I believe they didn't go over because of the (electronic) "trust" issues. A true craps player really wanted to see the physical dice in action. There were a couple other dice games... One was in an upright cabinet that did have 2 dice that were "tossed" out on the playfield and then drawn back to the front and electronic "eyes" read the dice and paid accordingly. I can't recall right now who manufactured them. They were short lived. The other dice machine was a JJ Parker console dice machine. I saw an ad in the paper one day for dice games for sale... went to a storage locker and purchased 10 of those monsters. Most of the JJ Parker dice were found on bar routes. Never saw one in a "regular" casino. Size: approx. 5ft long, 30" deep and 40" tall. Weighed about 300 lbs...NO Wheel casters. Electronics were electro-mechanical. There was a wheel inside with every possible dice roll / combination and a pair of dice in each cubby hole/section. You could bet on anything using a dial in front lighting up the "bet" ...inserting one to several quarters...and when finished placing bet / bets you pushed a button and the dice wheel would turn (while the wheel of dice was turning inside the machine, there was a "clacker box" / wooden box that had a couple balls on piano wire would emulate the sound of a pair of dice shaking in your fist before you tossed them out on the table ! ) Anyway, the dice would be shot out onto the field and payouts would come out of a Large hopper on wins ! An arm would shove the dice back into the wheel and ready for the next "throw" There was no space for the dice to "roll"on the playfield table...but rather just slid out and back. The machines were quite amazing in design. I never saw an actual manual or even advert for them. They all had hand written notebooks inside giving details of the service calls / repairs.
