Wasn't there a thing called a 'Thunderscan' that fitted into an Apple
Imagewriter and did essentially this?

I also remember a do-it-yourself project on this in Byte (back in the days
when it contained useful info...). I seem to recall it used a normal
dot-matrix printer, and a photosensor that you fitted onto the carriage.

I wonder how hard it would be to use a monitor (the smaller the better),
some optical bits and a photomultiplier tube to make a flying-spot
scanner. Seems like a fun project for a rainy day...

The gates in my computer are AND,OR and NOT, not Bill
