The game is finished. all the teething problems have been sorted. I had an issue with phantom door buttons closing while the door was closed which ended up being a prblem with U16 LM339. Replaced the chip and it works perfectly. I had the resident ST TNG Guru (Marco - Pinfan) play the game yesterday and he was happy everything was working 100%.
The last step was to install a new DMD display - the old one was good, but the bottom right hand corner was slightly fading. Not normally seen until the "Command Decision" feature lights up all pixels and you see 6-10 dark pixels. Would still be ok to leave the display in the game, but I wanted the game to be perfect. The game can have either black or chrome legs. Up to the buyer.
Final pictures ;
Will post a "For Sale" thread later today.
