What, no LCD display assembly? I would regard that as _essential_ on any
digital camera I had to use.

Is it possible to get any data on the sensor? From what I recall, driving
CCDs is 'fun' for suitable values of fun. The rise and fall times of the
drive waveforms are critical, for example.

I once saw a digital camera wit ha 2-position focus control (normal and
close-up). it dit appear to move the lens on a focussing mount. There was
no autofocus, or anything like that.
I wonder if you could use front-of-lence closeup lenses? The resolution
of the sensor in such a caerma is not going to be great, so I doubt you'd
notice any loss of qaulity.
