At one time. But I was muddle-brained and simply overlooked this. It should be fixed/improved.

How many times did I read this and not notice?!? You are certainly correct. If the number "8574" is replaced twice with "2803", then this would be correct. Thank you, Andrew. I really do appreciate this feedback. -Rob Severson

Just the first "8574". :-) -Rob

Does anyone know how can I get some AT45D081s? I found some dealers however they don't sell outside the USA or Canada. Since I live in Bolivia it's really difficult to get ATMEL items. Javier
