Found it! Rocket III Schematic

[astyy]

Last up, am looking for the schematic please, original or a copy would be great. I'm not going to get far without it and don't even know what the fuses should be, definitely not what's currently installed though

Looks factory to me dude

Edit: except that one on the right, dirty imposter!
