Right, I've stripped the system - I've pulled the Silversurfer and PCMCIA NIC, I've pulled the SCSI cable from the BPPC, all that remains is a Powerflyer, to which a HD and CD-ROM is connected.
The system won't boot, although I can feel warmth (not blazing heat) from the 060 and PPC chips, and I can get to the accelerators menu by pressing Esc. I suppose the next step would be to remove the BVision - why do I get the feeling that its impossible to fix to the accelerator with those little screws? How does one hold the nut for each screw in place when reattatching?
