Hi, so I purchased an outrun deluxe. Cabinet and art work in pretty good condition but nothing working. I started by repairing the monitor. Moving onto the pcb, voltages checked both red LEDs light but only rubbish on screen and looks like no sync. Checked sync with oscilloscope and no signal. Managed to find the 74ls125 buffer for video, sync in but no sync out. Now replaced. I have written and placed the 4 test roms in the cpu board. Still rubbish on screen but with sync now. Even though I have no info on screen, the test is being carried out as I get flashing brake lights and star button lights. The problem is I get 17 brake flashes and only three start flashes. I see that alot of the memory chips are not easy to get hold of. My question is, is it worth trying to repair? Is it possible its not all the memory chips but the memory control or buffer chips. Im just not sure. Maybe its worth me getting another pcb set but again there doesnt seem to be many around and when there is one available and working its alot of money. Any advice appreciated
Thanks Rick
