Gun Fight arcade game part 1

I bought this Gun Fight arcade game.
(Apparantly the first arcade game with a cpu, and the first with “human to human combat”.)
It is based on Intels 8080 CPU.

The cabinet seems to be quite nice for its age, only a small piece missing in the top left corner, and only a few scratches.

I also got a cardboard box with another monitor in it, a Philips 19VKUP22.
Does not fit this game though. 🙂

The game boards and power supply were delivered in a cardboard box, luckily together with an extra set of boards.
(Which were heavily hacked.. 🙂 )
The CPU and PROMs from the original main board were delivered desoldered and loose in the box.

I removed the transformer from the game and placed it on my workbench together with the power supply board.
The power supply board had also been worked on recently.
Two newer capacitors, one of them placed backwards (+/-), and the other one were in serial with a zero-ohm resistor.

This will be an interesting repair. 🙂

The power supply were repaired first and is now working. 🙂
