You might have damaged the Centipede pcb with 9 volts going through it. You can reseat all the socketed chips and hope for a miracle. Reseat the edge connector to the pcb too.

I would swap out the CPU and the pokey (yes, the pokey, as some data lines to ram run through it) with known working ones as a quick check. But, as Arc pointed out, the 9v could have killed a few things.
Ok here is a small UPDATE... I have a working AR2 board coming in the mail from andrewb. And Im also in the process of purchasing a CENTIPEDE PCB from brzezicki. Here is my question. Once the AR2 shows up my plan is to install it and use the faulty existing PCB as a test dummy just to check the +5V on the PCB and adjust it if needed before install the new PCB im getting from brzezicki. That way my voltages are checked before introducing the working PCB. Is that a good plan? Thanks.
P.S. The reason I ordered a new PCB is because I plan on using the old PCB to learn on.
Thank you sir.

Open the track ball and see what the rollers look like

We're not splittin' balls yet just let the man get the game on first! He can worry about that later![]()
The rollers weren't worn too bad? Lucky...
