I'm ChaRleyTroniC / Systeme D, sometimes known as Richard Fairhurst: ex-Amstrad Action freelance technical editor, Robot PD proprietor, BTL and WACCI editor, and coder of loads of stuff including RoutePlanner, PowerPage, ChaRleyTraCker and so on.
I have a working 664 once again (hooray) but sadly no 3.5in drive on it... yet.
