Re: A89: HW1, HW2, and HW3?




I was mostly guessing :)
I think more of the reserved bytes theory.
btw, the pdf describing the flashrom found in at least the HW1 calcs
(probably the same in HW2) is to be found at my page
http://alh.dhs.org/ti89/
I have only read through it breafly, so I don't know how it handles bad bytes,
but yes, flashroms mostly work as you described.
The chip is a LH28F160S3(T-L10) and is made by Sharp.
(the japs infiltrate a lot, don't they ;)
