17-18-19 are outputs. They allow to activate the 1852 in the IOS board with the 1853 decoder. You must have 5v pulses Have you got signal on adress bus and data bus ?

f I remember It's ok. If you see a wave signal it's good.

Hola
You mustn't see a clock signal in pin 1 ( 1802 ) but you must see the clock signal in pin 39.
Unplug the ios board and look at the pin 4 and the pin 17, 18 and 19 ( 1802 ). On the pin 4 you must have a signal and on pin 17, 18 and 19 you must have a pulse signal.

I agree. You have to remove the -5v and the +12v for the cpu and you have to change the strap close to the CDP1859 and close to the Eprom 11 too.

Where did you find the eprom source ?
If you use two eprom you have to change the jumpers. You needn't the -5v and the +12v for the cpu.
You'd do better to remove them from the cpu. The 2708 need - 5v and +12v but the 2716 only need +5v if my memory is still good.

Hi everybody
I'm still looking for the little board for the car in the backbox and some plastics for the bumpers.
Have you got that ?
Thank you

Hi

I cleaned the pinball and i fixed the power board.
I found some parts at recreativoslider but it's not easy to pay them from France. I don't know if i can.
I'm looking for the caps of the bumpers. Someone knows where i can find them ?
Thank you

Thank you Bladis for your answer

I forgot to introduce me. I'm living close to Toulouse in the South West of France. I'm not a gamer but I like to fix pinballs. I try to buy old pinballs fo fix them. I'm looking for Spanich pinballs like Playmatic pinballs.

Yes we are champion but we play bad but if you saw the last match, one shoot one goal !

I'll try to send some pictures of the lap by lap. I changed the side rails. I don't like plastic side rails.

Best regards

Hi everybody

I'm from France and I've got few pinballs. Sorry but I don't speak spanish. I love spanish pinballs. I've got three Playmatic ( Attack, Megaaton and Cerberus) and one Inder ( lap by lap ) . The lap by lap doesn't work because it lacks some parts ( door, the little display board for the car in the backbox, some plastics and the flippers ). So I'm looking for some used parts for my lap by lap. Do you known where I can find that ?
Thank you for your help
Best regards
