Nothing very radical in the BBC modified version. This small board is it:

Adds function to the start fader (not sure what, as mine doesn't work. The fader isn't the standard type and has two sets of connections. Don't know if it's just a stereo slider as I haven't took it out yet.
If you're getting yours fixed, get new tactile switches fitted. They cost nothing really. Replacing them is a bit of a chore (27), but they make a WORLD OF DIFFERENCE to the feel of using it, being a lot, lot, lot more positive in action. The originals feel tired and shagged-out, by comparison. Really worth the trouble.
The two surface mount capacitors (1uF/33uF) on the motor-drive board will have failed, more than likely. A good chance the lasers will be OK.
