I found a guy whos selling some old arcade machines which are:

- Jungle Hunt
- Alpine Ski
- Dig Dug

First, are these machines rare and worth anything?
They are all cocktail tables. Jungle Hunt is missing a controll panel and there are some wear here and there. The powercord are also missing on all 3 games for some odd reason..?

Is this any problem to fix this?
I dont have much knowledge about electronic components and stuff so can an average guy like me get these to work?
