Hi Erik,

Yes, that's a fair comment.
Perhaps I should be more generic and say, "Read the Documentation" ;-)

However, it does further emphasise my point that there is no answer to the question, "Can I erase an EEPROM by a universal programmer such as SuperProIII?" - it depends not only on the particular EEPROM in question, but also on the particular programmer and, as you say, its current software update status.
