Got a Chase HQ SCI pcb in recently to fix up. Love this game and want to run it on my chase hq upright as an alternative to the v1 game. This one I played more int he arcade is think back in the day.
The thing is dead, so looking about in case anyone has fixed these before or has suggestions. I have a clock pulse to the main 68000, main roms (4 of verify ok). Reset chip is working. Reset line to main 68000 is watchdogging. I am trying some replacement pals C09-25, C09-24 and C09-26.
Had a similar issue with the Sega golden axe 2 where the reset chip doesn't work unless you have a seriously powerful supply for 5v. Board is drawing about 3.3A when on at mo but nothing on screen
Any suggestions on what to check next would be appreciated if anyone has looked at these before
