I’m trying to convert a working -200 MPU from a big game to work in a bally strikes and spares that uses a -17 mpu.

I’m trying to follow the pin wiki instructions but can’t get it to boot. Here are the two steps I’ve done but Need a little help figure out what I did wrong, or if there are additional steps that I’m missing

I’ve attached photos of the steps I’ve done. I first downgraded to the mpu -100, and then I made the jumpers that strikes and spares needs on the -17 chart.

Thanks!

Your first screen shot is about the clock speed and the 2nd one is for ROM jumpers on the -17 MPU. You should be using MPU200 instructions

What kind of ROMs are you trying to use and can you burn new chips? I would recommend jumping the MPU200 for 2723 ROMs at U2 and U6. Then put two repeated copies of -17 game ROM data in chips. ie...

copy /b U2+U2 U2.732

Ok thank you. No, I don’t have the ability to burn ROMs so I’ll have to get those
