Looking really good. I can see how it works now. 👍

Here is a quick vid.the missus can't get past first hole. 20241229_211930.mp4

Smashed it

So back together after a few adjustments. Having tea then will test and if all OK will do a vid.

Will put a vid on when I've ironed out a couple of issues. Thanks for all your comments.

Fantastic work 👏

Amazing 👏

Superb!!

That looks so good simon .

Mostly together now,need to put drive chain on and make a few adjustments. This is what it looks like.

These books are fantastic and great value

Where is that square wave coming from? Pin 2 of the 555 will trigger if it sees the voltage drop lower than the set threshold. The aerial wire connects there too as it prevents people trying to trip the machine up using a spark generator. That would normally just be a noisy signal not a square wave? If it's 50Hz then it must be coming from one of the supply feeds?

Hello everyone. What I wrote tuesday is partially false. I' m sorry for that. There was a poor contact in the PSU socket, not because of the female pins (they are new) but because of the male pins. Maybe I will have to change them too to be sure. So, about IC1 NE555: On pin number 2 there is a square signal 3,7 V The tension on pins 6 and 7 is 3,5V and drops to 0V every 4 seconds. The voltage remains at zero for one second and rises at 3,5 volt during 4 seconds and so on. On pin 3 the tension is 4,1 V I just walk in the fog 😂

Looking great, when that playfield art goes in there, it'll be super close!

Here it is done,now for the final touches.so I've got to strip it all now.

Hello. Thank you Bob for your encouragement, I will not give up. I measured the tensions, I admit that I am lost. I wish everyone a merry Christmas. Here is a picture of a blockhaus on the beach where I live paint for the occasion.

Now all wired and tested..it works.now onto final finishing.may take a few days.

Hi

Hi

Hi

Thanks Tris. To be honest I just noticed those missing and got all excited without really looking what they did. Yeah, I agree, looks like they aren't needed.

It looks very impressive Simon, a testament to your skill 👌

The other two chips are UART related, so probably for some kind of data retrieval device on the 6 pin PL15 header next to them. If you don't have anything that plugs into that connector then you most likely won't need the chips!

No schematics I'm afraid. I've been through all the photos I took and I don't have a clear shot of that chip. However, I have seen photos of this board which are missing the same three chips, so maybe the game you have doesn't need them? You could ask Mr P, the machine was his.

All parts now made and fitted,will be wired up tomorrow ahd see if it works and if any adjustments needed. Then it all has to be stripped painted and artwork added.
