I've said it before but the video board needs to be reproduced. It's relatively simple for what it does and it could probably be easily reverse engineered. There are tons and tons of good donor CPU boards available from all the parted out Final Lap/Four Trax/Suzuka cabs. Having the video board...
I have a twin cabinet and you can set the slave side to act as a live monitor. With that said, you absolutely must have an IO board hooked up to the main PCB or it will not boot. Just in case you want to attempt to build your own custom live monitor setup. I do not know if you can omit the sound...
This is the control panel that came with the cabinet. I assume the original owner ordered it that way. It's not a repro. Yes, it is technically not the "correct" panel.

Super Neo 29 Type II
HOME USE ONLY! (Note: I have no way to prove this, but this is what I was told and the condition should speak for itself.)
I am the fourth owner of...
Trinitrons are not compatible with arcade monitors at all. (Aside from a small handful of extremely rare Sharp Image models that used a Trinitron tube from the factory)
Go to this website: tubular.atomized.org
Enter your tube number and get the specs of your tube. When you find another 27 inch...
I would be down for 1 or more. Can you post a picture of the PCBs of the correct revision cart? I have several 161's on hand but no idea if they are the right version.
Where did you buy your mod parts from? Did you buy the kit offered here or did you piece together the parts yourself?
Have you fully recapped your chassis just to rule that out?
Check your B+ voltage?
Looks like you answered your own question.
Taito pretty much always used negative 5 volts on all of their JAMMA boards. Yes, it is required.
Using a negatron is an easy way to get negative 5 volts. https://www.dimensionengineering.com/products/negatron
Just tap your 12 volt line and adjust...
