Quoted from Elevatorman:I picked up a Bally Radical from someone that bought the machine off someone in 1993 so I believe I'm possibly the 3rd owner.
My question is how do you tell if it's a true prototype or if someone added this stuff.
The extra slingshot has factory colored wiring harness as does the vuk. The ROMs have little silver stickers on them that say Proto.
I'll get some pics when I get it set up.
Just curious how many of these made it out of the factory this way.
Thanks.
Is the playfield Diamond Plated?
If so then it’s at least a sample. The prototype Roms would be present on a sample or prototype. Red lamp boards would be the main thing to look for on a true prototype.
