When you power up the everything seems right. All lights, attract voice and displays. All "0"s and alternating between high score. Gate cycles as it should in attract. When I push the start button ball eject pulses once a declining short tune plays for 3 seconds then nothing. When I do the the test button lights cycle, solenoids cycle. On step 20 for memory test "2332 2" is displayed on player 1 for 10 seconds goes out and then 99 is displayed on the ball display. Anyone ever see this on before?

I have the apron off. With no balls in the game and I hit the start it still tries to kick a ball. I put one ball in and hit the start and it did kick it up to the ready. Any thoughts on the temporary 2332 2 in player one window during memory test?

You may be right. During the system test all digits display correct but when I go into book keeping some segment of the digits are missing. What do you think?

Thank you, I'll be standing by.

Yes original 80 CPU
I've rung out connectors and all looks good. I don't get it everything looks right till you hit the start button.

Nothing is displayed in player 2 during test.

Waiting for the new 2332-2 chip and i'll post results.

Anybody have a R3272-12 ROM for Black Hole?

Listed part number on the schematic. Look at Frenchmarky posted in the thread for that code. By that post implies U3 is bad.

I saw the post of how to make an Eprom adaptor but where do I get the program data to load in it? Or am I incorrect?
Does anyone sell them?

Bought new MPU board.Everything is working.
