I'm not sure at all what you mean.
If you mean you like the more vanilla versions of the 4 circuit boards and the parts to make it, that's still there and not changed. If you want the fancy versions that bob changed to recently, you can use them too.
The option is under: Settings > Mod Setting > Startup > ShinyBobGFX > Use ShinyBobGFX circuits.
If you're talking about something else, please go to the forums so we can attach images because I'm not sure what you mean.
