Amp Power Connectors (Disc Drive)

Back to 8BS Thanks to Pete Turnbull for allowing me to use this reply that he gave to someone asking about power connectors for his disc drive:
They're AMP (now Tyco Electronics) connectors, though they've been obsolete for a couple of years. You used to be able to get them from Maplin and Farnell, though Farnell don't stock them any more (don't know about Maplin). If the AMP part numbers are any help, here's a file I contributed to one of the sites that lists pinouts (the Beeb power connector is at the bottom):
