anyone have the dimensions for an upright asteroids cab? i cant seem to find anything here and jakobud doesnt list it. the main thing at the moment though is to get upright dimensions and control panel layout.thanks in advance!! |

Funny, I was sure Jakobud had Asteroids plans. I don't know where else I would have seen them. Asteroids does have a cocktail version, it uses the same PCB as the upright version but is wired slightly differently (when certain pins on the connector are closed the PCB knows to flip the screen, open one players controls and close the other players controls; thats why the PCB only has inputs for one player) I've been waiting for an emulator that emulates cocktail Asteroids, but I don't think its ever going to happen :'( |

It depends on how you wire it. Read page 4 of this doc http://www.arcadedocs.com/vidmanuals/A/asteroids_2b.pdf Here's pics of the wirings schematics I took. http://photobucket.com/albums/v472/SirPoonga/asteroids/?action=view¤t=manual.jpg http://photobucket.com/albums/v472/SirPoonga/asteroids/?action=view¤t=harnesswiring.jpg http://photobucket.com/albums/v472/SirPoonga/asteroids/?action=view¤t=p2_wiring.jpg |

Right. So there's seperate grounds on the harness for Player1 and Player2. How do you think this could be emulated in Mame? Should there be a seperate rom set or a fake dip-switch added? Every few months I bug one of the Mame devs about adding cocktail support, and they show a little interest then give up. It'd be nice to see it happen some day. |
