I have a digital camera that is now (and in fact, as of last friday) 10
years old ;-)
Actually, I now ermember I do have a 'digital' camera on the
to-be-repaired [ole, and I suspect it's getting on for 20 years old...
It's a 'Datacopy 300'. Inside there's a linear CCD (one line of pixels),
probably around 2000 pixels long. It's moved across the image frame by a
motor and leadscrew, obviously this camera only works for static
subjects. Inside the body of the unit are half a dozen PCBs containing
the CCD drive electtronics, motor driver, ADC, intensity correction (the
output from the ADC is multiplies -- yes an 8*8 full multiplier chip is
in htere -- with a vulue from an EPROM, one location for each pixel on
the CCD, to correct for uneven response of the CCD)., etc
There is no itnernal storage or PSU. There's a DB25 connector on the
back. The interfac board I have for it goes i na PERQ OIO slot, I beleive
the camera then conencts to the PERQs 'laser printer' connector, which is
simply wired to pins on the OIO slot.
I've never tried to get it working, maybe I should...
