Yep... mine still has the plate, with all of the buttons, rocker switches, and printing intact.

Nope. The game selector just an 8-position pot, of which the last four selections are jumpered to the first four. The options are chosen by individual rocker switches for bat size per player, bat size, and Player vs Player/Player Vs Machine. There's also a start button. My cabinet currently has a 19" TV in it, with a PCB running the AY-3-8500-1 IC; the PCB of which I had fabricated from a French design. I didn't modify the control panel at all, but replaced the pots (which are tested bad) with 1M pots for my PCB, and wired the control panel to my PCB, with the reset line hooked up to a coin switch. The cabinet doesn't move from its spot in my game room, as it would probably crumble if I moved it again.

I have pictures if needed, and I kept all of the hardware and harness from the original game. Here's one of the control panel from an angle, post-mod, but before I printed new identifying vinyl labels for the switches for my mod. I can remove the vinyl and take more pics if needed.

Here's the rear of the control panel. the four player pots are in each corner of the cabinet, so you won't see them here:

Here are the PCB and jumper block wiring for my mod, with termite and water damage in the cabinet in tow:
