Hello,

I just successfully programmed some EPROMs of mine (27C256).

Ok, this is not very interesting in itself. Anyway, now, I wanted to
clear them again. Thus, yesterday, I put them in the sun (the whole
day). I hope them to be empty, but they are not. Both still contain very
many of the programmed bytes.

Does anyone here have experience how long I need to put them in the sun
to completely erase them?

Regards,
   Spiro.
