Some months back I started working on a Philips P3800 computer, there was a long discussion here about the power switch and its unusual cylinder lock. At least one person was interested enough in the lock to say they would like to see it with a view to making a key At the time I didn't want to post the lock anywhere as I could have been left with a incomplete and unrepairable machine. Other projects, some of them classic-computer related got in the way. but over the last few days I've gone back to the P3800 and have made a spindle to effectively replace this lock and allow the power switch to be knob-operated (security is not an issue in my workshop :-)). Thus I could manage without the lock if I have to. So if the offer is still open I would consider posting the lock somewhere (preferably in .uk) Obviously it's 'work on it as and when you feel like it'. There's a lot of electronics for me to work on, and I'll probably take many months to sort that out. -tony
