Faulty Apple Lisa 2/10 Drive - Problem persists

Yes. One advantage of what I call 'real' troubleshooting is that you tend to pick up quite a bit of electronics knowledge along the way :-) It's a pity that we live on opposite sides of the globe. If we were nest doro to each other, I'd suggest letting me have a look at it. Needless to say it's a lot easier to do this sort of diagnosis with the device in front of you. Well, I certainly do, and it does, indeed, keep growing. There's a lot of intereting stuff I must get round to working on one day. I tend to only put stuff there if I know it's going to takr a _lot_ of time to sort out (months/years) or if I know I need parts/manuals/knowledge that I can't get at the moment but might get later. I think in my case if I had a drive with a spindle motor problem I would see it through. YMMV -tony
