After a solid weeks work, making the box, applying vinyl wrap, drilling holes, fitting buttons, wiring buttons to controller boards my MFME keyboard is finished. I couldn't have done it without MPU_FIVE (Gary). His amazingly detailed shopping list made it easy to buy what I needed. His awesome guide on his own keyboard helped me get mine built. Thanks to ArcadeWorldUK for supplying the parts quickly and replacing my faulty led super fast (thanks Andy). Now comes the even more scary part. Getting the keyboard to work with fruit machines. That's the task for the weekend.
Attached are photos of prototype and final version.
