So I picked up a DE Time Machine. Through testing, I have determined that I need a power supply board. Which I have purchased (rottendog) and have yet to install. However, while inspecting the game I also noticed that this sort of daughter board was wired into the reset circuitry. What is it? What were they trying to achieve? Anyone have a clue?
I am limited in my knowledge of board work and am learning with a little help from a good friend.
IMG_20190913_193326 (resized).jpgQuoted from wayout440:It's just a simple 555 timer circuit to substitute for the 3 pin PST518B. Maybe they didn't have the part or wanted to alter the watchdog timing.

Awesome! Appreciate the response. I installed my new power supply board and the game booted up and works.
The only issue I am still having is when I plug in the GI to the power supply board the GI makes a increasingly quicker click sound while flickering the GI until the GI fades out. I am a little confused by this.
