This is my old MAME cab. I've done a few things to it. It doesn't have a monitor, or a pcb. I sold the old marquee and the original CP. I made a new custom CP that supports six buttons per player.
There's a bunch of other arcade things that I can't really recall shoved inside of it like buttons, stick parts, coin door parts, power supplies, transformer, etc. Probably some old pc stuff too.
The cab itself is in decent shape. There are many chips and scratches over most of the lower side of the cabinet, but it is very solid overall. I think it's missing one of the rollers on the bottom. It has also had a strange kick panel of some kind installed on it.
It's all yours if you come and pick it up. This stuff is taking up room in my old apartment and my former roommates want it out.
