I think that the floppies are much less reliable :-(. It is very easy now
to buy the "outdated" HD with capacity < 1GB which should be sufficient
for this purpose.

BTW I'd like to answer on the list questions I've received from different
readers regarding this project (to avoid answering individually all of them):

1) The project is intented to be the free open source project
   (with GPL or "artistic" license)

2) Addition of USB and other interfaces is appreciated, however at the
   moment I'm not interested in it (neither my camera nor my PC has USB).
   However the potential need for USB may influence the choise of proper
   uC. Any suggestions are welcome.

3) The device should be powered from the 12V (car battery?).
   BTW. What are the HD's requirements regarding the stability of +12V
   voltage? (Maybe it will be necessary to use a stabilizer/converter:
   +12V (batt. unstable) - DC/DC pulse converter -> +12V stabilized
    |
    +- DC/DC pulse converter -> +5V stabilized
