Got 2 DP pcbs (thanks rampage) that i am trying to get going.
It seems that both pcbs have the same fault as in just not powering up correcly.
Did a dump of the eproms to see if they were a Good Luck Draw Poker PCBs but none of the roms for eather set match anything.
Been over both sets with checking clocks resetting ect but it seems to be like the main cpu is just not kicking over. I get a clock pluse on the cpu and it isnt resetting and seems to be reading the eproms but thats it.
Taken all rams out and checked one by one in a working arcade pcb to narrow that out. The only thing left that i can think of and i have seen before on a Olympic draw card pcb is there is a relay that maybe not switching on or gone faulty causing pcb not to fire up.
I cant even find any RGB or sync out of the edge connector
