Ok someone who worked on this thing before and was able to get them working is amazing. info is not readily available. I picked up a machine with a broken chassis, dead 24 v power supply, and figure the Io board is not working because nothing on the shifter / e brake works.
After people finally paid me long story I was able to get to work on this puppy with a new 24v ffb power supply, and after going to Chucky Cheese for a friend's kid who loves me, I kind of liked how the new machines had a giant lcd screen in there well I figured I could so something like that and plan to do something like that with mine (wanted to stay original but eh). Tv Looks good but I am now on to this dang Nytric board. I am not even sure where to start to buy chips for it, or what I need to do. My problem sounded a lot like yours where your e brake stayed on, mine was just completely dead. Not a short that I am aware of but maybe a total failure. I also read those those 3 chips are likely to fail but is it just a mater of buying those you listed and replacing them or like with rom chips you need to load certain rom files on them? I am trying to learn here but starting out sometimes seems like you step in something and do not want to keep spreading it around the house so to speak. After this the next steps seem trivial but eh.
Might as well ask now anyway, I have a players card, but unable to access the career mode, or not know how as of yet. Was wondering if neopolss knew something or anyone else. Right now I am just focusing on the here and now with this nytric board.
Thanks for any help

Many thanks to pcjohn for the pointer regarding the potential for buffer chip failure. I would gladly buy you a bucket of beer for the bump in the right direction!
I followed the trace from the I/O card header pin that supported the e brake input wire and followed it through the circuit. I found two 74AC373's (octal transparent latch) and one 74HC4051 (8 channel analog multiplexer) that were my best guess at being the culprit.
Three chips shipped were $12 or so from Mouser. More for shipping than the parts.
I replaced the IC's last night and now every input works properly. Next step is to find out what fried in the monitor chassis and then clean and assemble the game.
Thank again and good day!
