It will take a while to find out, what is what and if it's working, so far I have seen 2 original atari dig dug's and a orginal 4 pcb donkey kong. keep you posted.

What was I thinking this afternoon when I said.... OK I will take them all 

Very nice collection.

Nice cab 

Did not have much time lately to but at last some results. Made a new backdoor.... Needed that before I start working on the CRT (got 3 little boy's at home who love to help dad even when dad is not around  ) And tonight I did some more woodwork, the bottom side of the cabinet was really rotten so I replace the wood panels. I must say that I'm happy with the result. Next step primer and black paint.

Very cool machine. I'm not an expert on this machine, but I will give it a shot. The movement knows three parts. 1 the engine part that makes the actual movement,2  the hardware and software on the motherboard, 3 sensors that decide how the movement should go. The last part I' m not sure about it could be that every move is just software based and not influenced by sensors.

BUT, at startup the testmovement works. So part 1 and 2 are working. That leaves three options, a specificpart of the software is corrupt ( highly unlikely), the movement option has been turned of in the setup, ( check setup and manual), last option most likely... Sensors or sensor wiring is dirty or broken.

Find the sensors by checking out the manual or just following wires, ccheck in the test mode of the software if there is a sensor, button test mode.

Good luck

Fixed broken wires and CRT grond strap.

QUESTION, One of the springs for the ground wire was missing so I used new springs to fix the ground. New ones are not so strong and little bit bigger in diameter. Is this ok? See picture.

Whooo, pretty depressing setting, 1983. Still cool find, remember the song not the clip.
