Hi everyone.
-Background-
Machine is s/n A 13393, acquired in the mid-nineties as "cool", with an equally heavy box of manuals, software, & accessories. It worked fine then, and has been mostly a closet queen since. Some years ago the display booted slower & slower and then not at all, so I figured dried caps and put it deeper in the closet.
I remember Osbornes but never had my own. I'm not very experienced with vintage hardware. I started with the PET and naturally by now I'm very good at fixing x86 boxes, but I've never been a professional technician.
-Actual Question-
It boots the display screen now, surprisingly enough, but that's all. It does not respond to the keyboard, and it is silent other than the beep & quick flash of the drive lights at power-on. Memory tells me the drives used to react to having a disk installed - correct? This one is stone dead other than showing the boot screen. I've tried booting B with the shift-' key combo.
Not sure what I should poke next. I guessing this may sound familiar to the Osborne-experienced here, so ought to ask.
