This camera has 640×480 resolution with built-in memory and a serial interface, holding about 16 pictures. There is no USB nor memory card slot.
This camera was designed as Windows-only, with proprietary TWAIN drivers to talk to the camera over the serial port.
Work was done to reverse-engineer the serial protocol for GPhoto 2. It works, and I was able to get pictures from the camera as PPM files using gtkam and the gphoto command-line tool.
In my testing, the colors are slightly different in the gphoto output, compared to the Windows Twain driver output.
The Fun! Flash 640 is different from the PDC-640 and 640SE models. Web references for the Fun Flash 640 are hard to find in 2005. Most searches turn up information about the PDC model. I recommend GPhoto as the main resource for technical details.
