Now that I'm back at home, I gave the Duo 230 (the dead one) a try with the MiniDock, floppy drive and external monitor, and sure enough it does boot off the floppy disk and activate the external monitor, so it appears that the internal screen is dead as well as the hard drive missing (and possibly the speaker dead too, as it doesn't chime). However, I just get the grey background screen on the external monitor and the cursor appears if I roll the mouse across, so presumably it is making an extended desktop on there as I can hear the floppy booting but can't see the desktop icons/menu bar, and I can't see anything on the keyboard to switch it into mirroring (and can't see the control strip of course!). I tried starting up with the lid down, but it still insists on using the internal screen as the primary display. Anyway, this does confirm that this Duo is totally dead, given that the internal screen is not working :'( I can't see anything on the screen at all - it looks completely dead, as opposed to just a dead backlight where you can still see faintly (if these screens even work in the same way as the newer LCDs). I'm going to get the other one, the 210, out soon anyway, and get OS 7.6 set up on it
