Hi everyone,
My first post here, so please excuse by noobiness...
A friend of mine is financially in a tough spot and I try to help her to sell some of her stuff.
Lo and behold, I found a very good condition Head-On-N cocktail arcade table in her attic!

The table looks in quite perfect condition for being 32 years old...
It seems it used to be a Nintendo HEAD-ON-N game, judging from the front and side plates

But later probably refitted to PacMan and Pengo

Also the inside looks in decent condition with the one exception of the missing monitor:

Here are the Joystick, buttons and some wiring. All wires seem to be in place and connected except of course for the missing monitor:

Some wiring diagrams in Japanese:

And here finally the front and back of the original CPU/Mainboard:

I hope you enjoyed the pics

Now to my questions:
1. As I'm trying to maximize the sale price for my friend, would it be advisable to sell the table as is (keeping in mind that the monitor is missing) or would it be better (money wise) to convert the table into a MAME unit and sell the CPU/mainboard separately?
2. If the latter, where would be the best place to sell such a mainboard?
Thanks for your advise!
Marc
