several videos on youtube about people using the drive sections and parts of them.
If your talking 1200x1200 dpi at 24bit resolution I am not sure the poor little chip could keep up at 16Mhz but it looks like a fun little project if you have a couple old scanners laying around and some free time. I see them all the time at garage sales, recycle centers and thrift stores.
The worst that could happen is it does not work?
