Hi, I have rescued an original Spiderman arcade, but its main board is a little rusty. I haven't archieved to boot it.
The Spiderman rom board works because I have tested it with the main board of my Golden Axe 2 game. I have measured the pulses on the NEC V60 and Zilog and there is activity. Also, in the photos, I have desoldered and tested externally all the TTLs and rams involved in the CPU boot up.
Also flashed a new 315-5441 PAL, changed the crystal oscillators. No cigar.
I have put a photo of what the game does when powering it up. It begins 1 second of black screen, and then in a blink it wants to show something and after that constant black screen.
Any ideas? Any help is welcome.
