Sansei R&D machine card unit connection questions

[Mr. Squeezable]

So, after playing around with the machine some more, I did find that it pays out fine as I throw balls in all of the payout slots when I had the door open. So, good on that. I did get some parts and built a CR bypass dongle. I was skeptical about it working, but I plugged it in and it got rid of the "Card Unit Not Connected" error code 7. It actually enabled the shooter to launch balls. The ball loan buttons and credit display don't operate, but that doesn't seem like this dongle would do that with the connections it has. So, I have high hopes that the DaveRob card emulator would work fine. Hoping they become available in the near future. CR bypass 1.jpg
