> - A mid-summer Northern emisphere location at Sea level, 60% humidity, > sunny exposure (75% of total sunlight): ~ 15 days I doubt that the EPROM is *really* erased after that period. Have a look at this: http://www.rottmerhusen.com/etronisch/eraseprom/eraseprom.html (Explanations in German, but Babelfish should do a somewhat good job on it.) Apart from the erase patterns (see animated GIFs), the really interesting part is that even when using an EPROM eraser until the EPROM is erased (3 minutes worst) data comes back when you lower the supply voltage from 5V to 3V. To surely erase an EPROM it takes 10 minutes. Rainer Message was sent through the cbm-hackers mailing list
