This is also a good learning exercise, the guy who gave me the board has a whole box full of dead MVS 1FZ boards, I can get them for free as he needs the space. So I took this one as an opportunity to get into the layout and workings of the MVS and so far, I've already learned a lot, but not enough. The fault has to be somewhere
This is the story so far:
Swapped out with no effects, same fault: 68k, NeoC1, NeoB1, NeoE0, NeoD0, Wram+Bram, SysROM->NeoDiagRom, 74HC259
What exactly does the 74HC259 for example? I can't make it out on the schematics, some address decoding I assume? What else could it be?
Is there a complete pinout for the upper and lower WRAM (1+2)? I've only found the one for both BRAMs (3+4).
Update: We have a heartbeat. After I've found a loose Pin (32) on the replaced Neo D0, the board now starts with a fast click of death.
