Same! Same!) - Toaplan 1990 (repair log)]&lt;br&gt;<br /> <br /> The board is in very good condition. However after powering it, it&#039;s stuck on a work RAM error:<br /> <br /> [[File:ApocFSH 1.JPG]]<br /> <br /> To me the work RAM should be the one connected directly to the main CPU (68k). As the 68k is a 16 bit processor the work RAM is actually 2 RAMs type 6264 (one for the LSB, one for the MSB). So I pulled both (@ J10 and L10) and put 2 fresh ones instead. No results. As I was unsure I replaced the work RAMs I contacted Caius from jammarcade who confirmed the work RAMs are the ones connected to the main CPU. I put the board aside and few weeks later it didn&#039;t boot at all. I had to reflow the big SMD custom chip @ J18. Back to the work RAM error...<br /> After some more weeks I decided to check traces around the work RAMs and found 2 bad. I patched them and the game booted:<br /> <br /> [[File:ApocFSH 2.JPG]]<br /> <br /> [[File:ApocFSH 3.JPG]]<br /> <br /> Game fixed.<br /> <br /> <br /> [[Category:Repair Logs]]</div>
