It's a basic Pac-Man front game, that has a gambling game hidden inside. The purpose of this "stealth" game, is just to be a "camouflage" for the real gambling game, for locations where the gambling games are forbidden. How to play the Pac-Man front game: Just Coin using Coin A or B, Start the game with START button, and use the arrow keys to control the Pac-Man. How to play the Pac-Man gambling game: Just coin up using Gambling Coin In (key 7). All ghosts will be placed around the center. (each ghost represent a number). Bet using START, and once done, press UP (deal), to allow the pacman eat all ghosts, revealing the five numbers (like italian poker games without cards). Now you have an arrow as cursor. Place it under the each number you want to discard and press START to eliminate the number and place the representative ghost again in the original place outside the center. Once done, just press UP (deal) again, and pacman will re-eat the new placed ghosts, revealing the new numbers (as a new deal). If you have a winning hand, you can press DOWN (double-up) to get a Double-Up, or UP (deal/take) to collect the winnings. If you're playing the Double-Up, choose left or right for Big and Small. If you win, you'll get the bet amount x2. If you lose, your pacman will die. Coin with A or B to exit the gambling game and play the ultra-adictive pacman front game again!... *************************************************************************** Unknown Pac-Man gambling game technical notes... The program checks the port 01h, bit7, for the sound hardware type. - Type 1: AY-3-8910 mapped at 17h, 27h, 37h. - Type 2: Unknown device mapped at 20h, 30h. I strongly think is selectable through a switch, so I hooked one till we have evidence of the contrary. **************************************************************************** Hardware Notes: (unknown 'Space Invaders' gambling game) --------------- Based on chip manufacturing should be manufactured in 1998 Specs: ------ 1x Zilog Z0840004PSE (4MHz Z80 CPU). 1x GI AY-3-8910 (sound). 1x LM356N (Low Voltage Audio Power Amplifier).
