Hi guys,
This is probably going to come across as a crazy post, but I'm not sure what else to do other than post the situation -
I've bought a MKI cabinet, that had been converted into Tekken3, with the intention to using it for my first MAME project.
I took apart the internals and put them to the side as I worked on restoring the cabinet and building the control panel...now that I'm ready to revisit testing/putting the pieces back together again, I"m completely lost because I was an idiot and didn't take pictures of where everything was connected (

I do know that the original game/machine was working when I first bought the cabinet - I do remember the game looked a little color dim
I know some of the pieces but not all and I'm not really comfortable trial & error connecting things together. I didn't know what else to do but to take an inventory of the pieces and connectors and hope that someone can help me identify the pieces/match or provide any guidance...
My end goals:
- I've bought a JPAC with the intention of connecting the original arcade CRT via the Jamma board. I'm still reading onwards to figure out if I should get a dedicated arcade VGA or if I should just try to configure it via software (soft 15khz, etc.) - undecided still
I've bought the following 2-player joystick/button kit, which I understand will not connect into the Jamma but instead directly into the USB of the PC & the LED buttons will be powered by the PC power supply:

I plan on using computer speakers for the sound which would go directly into the USB
I plan on purchasing this coin mechanism - I'm not sure how it will connect, but I believe it would connect via the JPAC into the Jamma board:

With those goals stated, I'm attaching pictures of the inventory I have of things I'm either unsure of what they are, or where they go in relation to connecting to one another. If anyone is willing, I'd really benefit from help identifying the pieces and understanding where they match/connect to. Thanks for any help anyone is willing to provide...I'll attach the pictures in this post and one follow up post....not pictured is the JPAC
