That is one hot lookin' Congo! I'm really pissed at myself for letting mine go some years ago, and am now on the lookout for another... actually found one for sale last night, but will require a 1200mile round journey to get it and will cost me twice as much as I sold mine for!! Still, seriously thinking about it, and seeing yours in that shape has strengthened my determination to get it!
Well done dude!
Lots of similarities on the playfield layout to Tron I've noticed... not that that's relevant, just an observation...
