Hi,
I've got a relatively clean Konami board for "run and gun" that does not boot. Unfortunately, I'am finding little info on this one.
Program rom and sound rom has been tested ok.
I looked at the reset signal which seems to to through a pair of ls04 and Konami 53252. I cannot find yet where it is generated.
Looking at data and address line on the 68k seems to look with my signal analyser.
Maybe work ram issue can cause this ? (Which one are they ?)
There is a test switch on the board but the board fails to enter test mode.
Any orientation?
Thanks a lot
