I’ve added a gallery of all the pictures taken when restoring an 80s arcade unit back in 2011. I tried to reuse as many items as I could, the controller unit was hacked out of an old keyboard, I used a CRT monitor to try and keep the original look of the machine (drove out to the country to find one!), the speaker literally came from the side of the road, the motherboard, disk and power supply were out of some random old computer. The only bought items were the small amplifier module for the speaker and of course it needed new buttons and joystick.
The biggest thrill for me I think was when the coin mechanism was working again and wired in.
The pictures are pretty much in the order taken, for a quick idea check out the first and last one!
