Hi everybody

I make a MPU V for some Playmatic pinballs but I have some problems with my board. So I need your help.
The power part is working, the cpu part seems to work too. I have a problem with one ic ( CD 4028 ). Some MPU V use a CDP 1853 and others use CD 4028. I choose CD 4028 because it is easy to find and it is cheap. But I think there is a mistake on the scheme from idpb or tecnopinball. I am looking for someone who has got a MPU V with a cd 4028 ( U7 ) to verify the connections with the other ic.
Thank you for your help.

Michel

Hi everybody

Some news about my mpu V

I tested it in my Megaaton and the lights are working.
I made some little mistakes on my pcb as you can see on the picture so I will order another pcb without the mistakes.
I want to test the displays but I can't do it with my Megaaton because it uses a mpu 3 and the displays don' t work with a mpu V. I must change some components on the MPU V if I want to test it with my pinball. So I am looking for a display board for a MPU V and a sound IV too.
Have a nice day.

Michel

I wish I could help you, but unfortunately I do not collect Playmatic SS pinballs.

Hi everybody

mpu_V_3

My Mpu V is working !
This is my new mpu. In fact, this is either mpu III or MPU V. I just have to change some components on the board. I tested my MPU in my Megaaton. This pinball uses a mpu III. I can play. No problem. I just have sometimes some problems with the music. I have to fix it.
Now I am going to test the mpu v version.

Best regards

Michel

Thank you.
I think I solved my problem. For some logic ic I use 74ls373 and I should use 74hc373.

Hello everybody

My MPU Y is working like a MPU III in my Megaaton ! I can play without problem.

mpu_V_4

Now I will try to improve it because for the MPU III I made an adaptator for the displays. I will put it on the pcb. The regulator 5V and the big resistor close to the regulator are very hot. I do not know if it is normal.
I will try it like a MPU V too in another pinball but I haven't got it so a friend of mine will try it.
Have a nice day.

Hi everybody

Some news from France. My MPU-III and MPU-V are working. I can test them on test boards.

test_boards

Now I can build them. One board for the MPU-III and one board for MPU-V because the connectors of the displays are not the same.

mpu_III_web

I am waiting for the last components ( sockets, resistors and transistors ).

Have a nice day.
