/*************************************************************************** IMOLA GP by Alberici todo: - document remaining dips - bogus colors - need better mappings for accelerator/shifter - eliminate need for master-cpu communications hack ======================================== www.andys-arcade.com Dumped by Andy Welburn on a windy and rainy day 07/07/04 Possibly has clk/dir type steering. Shows RB BO ITALY on the title screen and is a top-down driving game, a lot like monaco GP, it even has stages where you have headlights. Board colour, screening, track patterns, and most importantly component type and colour of sockets indicates to me a pcb made in the same factory as 'Sidam' and some 'Olympia' games. There is no manufacturer name, no game name, all i see is : AA20/80 etched on the underside of the pcb. I have had this pcb for a number of years, i always thought it was some sort of pinball logic pcb so didn't treat it too well. When it came to clearing out my boxes of junk i took another look at it, and it was the bank of 4116 rams that made me take a closer look. I hooked it up and saw some video on my scope, then it died. The +12v had shorted.. Suspecting the godamn tantalum capacitors (often short out for no reason) i found a shorted one, removed it and away we went. It had separate H + V sync, so i loaded a 74ls08 into a spare ic space and AND'ed the two signals to get composite, voila, i got a stable picture. The colours aren't right, and maybe the video isn't quite right either, but it worked enough for me to realise i had never seen a game like it, so i dumped it. I couldn't get any sound out of it, could be broken, or not hooked up right, i would suspect the latter is the case.
