Why not simply convert the Mr. Do machine into a MAME cabinet?

You realize that there are interface boards that allow you to plug its controls and its monitor directly into your PC, so that the only thing you'd need is the PC.

I would understand not wanting to mess up a classic arcade game in good condition in order to make a MAME cabinet, but:

1. It's not even in working order, based on what you said.

2. Come on, it's Mr. Do.
