Title: Time Pilot board issues Post by: adamtoth on October 29, 2016, 04:28:43 pm Hey everyone,
I installed a high score save kit on my Time Pilot (had to desolder z80 and solder a socket for daughter card), and then sooooo stupidly plugged in the edge connector backwards. I saw the game boot up to garbled video, realized my mistake, and quickly shut it off. When I switched it back proper, it booted up, displayed garbled video, and had no sound with the high score kit daughter card. I removed the high score kit, put back a regular z80 in the new socket, and now it has sound, but still garbled video. I must have fried something on the board. There are no obvious signs of anything burnt or discolored traces, the board is quite clean. Anything I can check to start eliminating culprits? I am thinking that a pair of diodes that are in-line just after the 12v pin on the edge connector might be toast. How do I test those? Those have 135 printed on them.
