after looking around on the interwebs i could not for the life of me find a parts list for these boards... the cpu board is probably the worst, cause having to find a part on 4 pages of schematics kinda gets abit much at times.
why did data east not add this? i mean gottlieb and williams did with their games?

anyhow
so i figured do it once and its done. took awhile lol and was not the most fun job but it needed to be done.
i have received so much free info from others its kinda time to repay abit, maybe someone finds this usefull. i know its surely making my life abit easier now.

here is the cpu boards part list, now this is not 100% complete yet or pefect maybe someone can assist somewhat in some of the areas i had questions to. everything with a question mark next to it i did not know what to make of what they saying in the schematic. also i might have missed something or made a error or two lets call this a work in progress
-----------------------------------
this is for all DataEast/Sega Version 3 cpu boards.

* all resistors are 1/4 watt unless otherwise indicated
* check cpu board assembly diagram in game manual for parts locations

okay well like i said. i might have made a mistakes and i did...
R2 should be 3.3k not 33k, the manual i had in pdf i could not make out the dot.

im working on a board now i made the mistake to put in a 33k lol, so after some searching and seeing voltage problems in that section i checked another schematic and low and behold problem.

Quoted from Bax1:

Marco-Thank you for taking the time to do this. This is a big help!!!

no stress i was abit tired of the where is waldo thing trying to find parts so it was just something that needed to be done, ill probably update it some more as i figure out more stuff.
